[jira] [Created] (CASSANDRA-19512) Add startup flag to load a local snapshot from disk
Paulo Motta created CASSANDRA-19512:

Summary: Add startup flag to load a local snapshot from disk
Key: CASSANDRA-19512
URL: https://issues.apache.org/jira/browse/CASSANDRA-19512
Project: Cassandra
Issue Type: Improvement
Components: Local/Snapshots
Reporter: Paulo Motta
Assignee: Paulo Motta
Add startup flag "cassandra.load_snapshot_unsafe=snapshot_id" that loads a
snapshot with the specified ID into the sstable tracker in the initial startup
phase.
The flag has the {{_unsafe}} prefix because it may cause data consistency
issues if this is used incorrectly. For example, if a given snapshot is loaded
in a single replica of a replicated keyspace, it may cause replicas to go out
of sync. For this reason, this flag should only be accepted if the
"allow_load_snapshot_unsafe" guardrail is enabled (it is disabled by default).
When the flag is detected during startup, snapshots with the given tag will be
located. If no snapshot with the given tag exists, the startup should fail.
The snapshot loading mechanism should create a hard link to existing sstables
into a staging area to ensure the existing data is secured. After this, it
should replace the existing sstables with the snapshot data into the sstable
tracker before proceeding normally with the startup.

[jira] [Commented] (CASSANDRA-17401) Race condition in QueryProcessor causes just prepared statement not to be in the prepared statements cache
[

Paulo Motta commented on CASSANDRA-17401:
-
Thanks for the detailed reports and repro steps. I've taken a look and this
looks to me to be a legitimate race condition that can cause a re-prepare storm
under large concurrency and unlucky timing.
My understanding is that [these evict
statements|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/cql3/QueryProcessor.java#L735]
are not required for the correctness of the upgrade compatibility logic and
can be safely removed. Would you have some cycles to confirm this [~ifesdjeen] ?
In addition to this, I think there's a pending issue from CASSANDRA-17248 that
can leak prepared statements between keyspaces during mixed upgrade mode. Since
these issues are in a related area I think it makes sense to address them
together (in separate commits) to ensure these changes are tested together.
I think the {{PreparedStatementCollisionTest}} suite from [this
commit|https://github.com/apache/cassandra/pull/1872/commits/758bc4a89d7ca9d0bfe27e6f41000484724261bc]
can help improve the validation coverage of this logic. That change looks
correct to me but may need some cleanup. We should probably keep the metric
changes out of this to keep the scope of this patch to a minimum.
After proper review and validation I think there's value in including these
fixes in the final 3.X releases to address these outstanding issues as users
will still do upgrade cycles as 5.x release approaches. This will make
resolution more laborious as we will need to provide patches for 3.x all the
way up to trunk + CI for all branches. What do you think [~brandon.williams]
[~stefan.miklosovic] ?

> The race condition looks like this:
> * Thread1 enters _prepare_ method and resolves _safeToReturnCached_ as false
> * Thread1 executes eviction of hashes
> * Thread2 enters _prepare_ method and resolves _safeToReturnCached_ as false
> * Thread1 prepares the statement and caches it

Looks like this is failing consistently in both 4.0/4.1:

*
[https://butler.cassandra.apache.org/#/ci/upstream/compare/Cassandra-4.0/cassandra-4.1]
[~e.dimitrova] I wonder if this should've been addressed by CASSANDRA-16684 or
if it's a new issue. I am able to reproduce the failure locally on
cassandra-4.1, even after increasing rerunsOnFailure from 2 to 4.

risky to me; I hope I do not overengineer it. WDYT?
{quote}
As far as I understand there is no reliable way to detect if there's a local
JDK other than check if javac exists in JAVA_HOME or PATH. So the only way to
figure out if the user is running on a JDK is to to check if javac exists in
JAVA_HOME/bin first, if not check on PATH - this does not look like
overengineering to me. What do you mean by "expect users to do more
modifications to PATH to adhere"?

Thanks Ekaterina!
bq. 1) Decide whether we want to be checking for runtime or javac (considering
the case I mentioned)
I think checking for 'javac' should be fine when JAVA_HOME is not defined. If
JAVA_HOME is defined, then we check for the existence of
"${JAVA_HOME}/bin/javac" to determine if it's running on a JDK. Would this fix
your edge case?
bq. 2) IMHO, we should not prevent all sjk commands from running if JRE is
detected
sounds good to me, the warning from sjk itself {{ERROR 14:04:02,644 Java home
points to /Library/Java/JavaVirtualMachines/temurin-17.jre/Contents/Home make
sure it is not a JRE path}} should be sufficient

https://github.com/apache/cassandra/commit/475c0035e6e04526eaf50805d33156ac9b828ab6
Resolution: Fixed
Status: Resolved (was: Ready to Commit)
Thanks Brandon and Stefan.
I'm confident these failures are unrelated so I optimistically committed this
to 4.0+ on
[475c0035e6e04526eaf50805d33156ac9b828ab6|https://github.com/apache/cassandra/commit/475c0035e6e04526eaf50805d33156ac9b828ab6]
to avoid dragging this for any longer given current CI restrictions.
I created CASSANDRA-19259 to address these failures separately. We should
attempt a green upgrade CI run before next 4.0/4.1 releases.

This is an automated email from the ASF dual-hosted git repository.
paulo pushed a commit to branch cassandra-4.0

The following commit(s) were added to refs/heads/cassandra-4.0 by this push:
new 475c0035e6 [CASSANDRA-18999] Gossiper::hasMajorVersion3Nodes returns
true when a cluster is upgrading patch version without Cassandra 3 nodes.
475c0035e6 is described below
commit 475c0035e6e04526eaf50805d33156ac9b828ab6
Author: Isaac Reath
AuthorDate: Fri Jan 5 12:57:21 2024 -0500
[CASSANDRA-18999] Gossiper::hasMajorVersion3Nodes returns true when a
cluster is upgrading patch version without Cassandra 3 nodes.
This commit fixes Gossiper::hasMajorVersion3Nodes so that it does not
return true when all hosts have a known version, no hosts are on a version
earlier than 4.0, and there is a 4.x minor version or patch version upgrade in
progress. Additionally, this commit improves the clarity of
Gossiper::hasMajorVersion3Nodes's name to indicate that it will return true
when the cluster has 3.x nodes or if the cluster state is unknown, matching the
description in the in-line comment.
patch by Isaac Reath; reviewed by Paulo Motta and Stefan Miklosovic for
CASSANDRA-18999
Closes #2967

Paulo Motta commented on CASSANDRA-19259:

[~stefan.miklosovic] can you try to reproduce this locally if you have a dtest

I want to check if this reproduces locally or if it's a CI issue.

Paulo Motta commented on CASSANDRA-18999:
-
5.0 precommit tests are looking good.
I can't make a lot of sense from the [upgrade dtests
failures|https://app.circleci.com/pipelines/github/driftx/cassandra/1444/workflows/ddfe8a3c-4b36-4b9e-8f01-c85249fd8488/jobs/70142/tests]
but they don't seem related to this ticket.
It looks like in both runs tests from {{upgrade_through_versions_test}} failed
with:
{noformat}
Problem starting node node1 due to [Errno 2] No such file or directory:
'/tmp/dtest-jbrcckw7/test/node1/cassandra.pid'
{noformat}
This looks like an environmental issue to me as I didn't find any open ticket
for this particular issue. While the
[4.1|https://app.circleci.com/pipelines/github/driftx/cassandra/1444/workflows/ddfe8a3c-4b36-4b9e-8f01-c85249fd8488]

seems to have gotten stuck.
I'm inclined to commit this to avoid dragging this ticket longer and re-run the
upgrade dtest before the next 4.X release to catch any outstanding upgrade
issues. WDYT?

Thanks Brandon! Looks like {{test_read_from_bootstrapped_node}} already failed
in
[5.0-j17|https://app.circleci.com/pipelines/github/driftx/cassandra/1446/workflows/e0726e79-e517-4a82-828c-c7931fc9d99b]
but this is being tracked in CASSANDRA-19097.
I will check back when CI finishes and commit if it looks good.

[jira] [Updated] (CASSANDRA-19248) "nodetool bootstrap resume" starts unnecessary streaming session on joining node

Paulo Motta updated CASSANDRA-19248:
Description:
Calling {{nodetool boostrap resume}} triggers a new bootstrap streaming session
on a joining node, even if there's a bootstrap streaming session currently
running.
Each time this command is called, a new bootstrap streaming session is started,
causing the same data to be needlessly streamed from peers.
It should only be possible to call {{nodetool bootstrap resume}} if a previous
bootstrap attempt has failed.
An example of multiple invocations of {{nodetool bootstrap resume}} in a
joining node is shown below:

{quote}I have tested 5.0 already, links are in my last comments above. Have you
done some changes to it? I think 5.0 is fully covered, the only thing we need
is upgrade dtests for 4.0 and 4.1.
{quote}
The 5.0 version you submitted was based on the
[CASSANDRA-18999-5.0-hasMajVer3removal|https://github.com/apache/cassandra/compare/trunk...instaclustr:cassandra:CASSANDRA-18999-5.0-hasMajVer3removal]
branch which removes {{hasMajorVersion3Nodes}} from 5.0.
We need to submit CI for [this
branch|https://github.com/pauloricardomg/cassandra/tree/cassandra-5.0] where
{{hasMajorVersion3Nodes}} is fixed but not removed (the removal will be done on
CASSANDRA-19243).
We also need to submit upgrade tests for 4.0/4.1/5.0. Can you do this in
circle? If not I guess we'll have to wait until asf ci is bac.

I created CASSANDRA-19243 to have a wider review on removal of pre-4.0
compatibility code.
For this ticket, let's just merge the original 4.0/4.1/5.0 PRs fixing
{{Gossiper::hasMajorVersion3Nodes}} without removing pre-4.0 compatibility code
from 5.0:
I have prepared the patches for commit:
*
[cassandra-4.0|https://github.com/pauloricardomg/cassandra/tree/cassandra-4.0]
*
[cassandra-4.1|https://github.com/pauloricardomg/cassandra/tree/cassandra-4.1]
*
[cassandra-5.0|https://github.com/pauloricardomg/cassandra/tree/cassandra-5.0]
I've submitted a [devbranch
job|https://ci-cassandra.apache.org/job/Cassandra-devbranch/2649/] for the
cassandra-5.0 branch but it seems ci-cassandra.a.o is unavailable.
I don't have circle environment setup, so I will wait until jenkins is back or
someone submits a circle job for cassandra-5.0 before committing this.

It was identified on CASSANDRA-18999 that {{Gossiper::hasMajorVersion3Nodes
}}was removed from trunk, effectively removing pre-4.0 compatibility from trunk.
This [PR|https://github.com/apache/cassandra/pull/3004] removes the method
{{Gossiper::hasMajorVersion3Nodes}} from cassandra-5.0 branch, which removes
pre-4.0 compatibility from 5.0.
In addition to reviewing the changes above, we need to ensure that no more
pre-4.0 compatibility code remains in 5.0+
Since the backward compatibility code will be removed, I propose adding a new
StartupCheck to prevent upgrade from version < 4.0 and a flag to override (if
this is not already there).

[jira] [Commented] (CASSANDRA-19001) Check whether the startup warnings for unknown modules represent a legit problem or cosmetic issue

Paulo Motta commented on CASSANDRA-19001:

I finally got a chance to take a look at this, apologies for the delay.
It looks like the [JDK detection
check|https://github.com/ekaterinadimitrova2/cassandra/blob/613bb6d2cbc40924479eac044f78e0c4e584521b/bin/cassandra.in.sh#L153]
does not work when the JRE is on {{/opt/java/openjdk/bin/java}} which is the
case for the official docker image. I updated the check [on this
commit|https://github.com/pauloricardomg/cassandra/commit/97472afcc4f63291ebbbcc6aab476b0ccf12ce06]
to check for the presence of the {{javac}} executable on the {{$PATH}} or
{{$JAVA_HOME}} to detect whether a JDK is present. Let me know what do you
think.
I checked that no more warnings "Unknown module: jdk.attach specified to
--add-exports" are logged during server initialization, nor when calling
nodetool commands when using JRE17:
*BEFORE:*
{noformat}
$ docker run --rm -it cassandra:5 nodetool help | cat | head -n10
WARNING: Unknown module: jdk.attach specified to --add-exports
WARNING: Unknown module: jdk.compiler specified to --add-exports

[(-u | --username )]
[(-pw | --password )]
[(-pwf | --password-file )]
[(-pp | --print-port)] [(-h | --host )] []
{noformat}
*AFTER:*
{noformat}
$ docker run --rm -it cassandra-test:5.0-19001 nodetool help | cat | head -n10
usage: nodetool [(-pw | --password )]
[(-p | --port )]
[(-pwf | --password-file )]
[(-pp | --print-port)] [(-h | --host )]
[(-u | --username )] []
{noformat}
I also checked that nodetool sjk fails with this message on JRE17:
{noformat}
$ docker run --rm -it cassandra-test:5.0-19001 nodetool sjk jps | head -n10
ERROR 17:22:29,631 Java home points to /opt/java/openjdk make sure it is not a

But works when a JDK17 is present:
{noformat}
$ bin/nodetool sjk jps
22825 org.apache.cassandra.tools.NodeTool -p 7199 sjk jps
{noformat}
I checked that all commands above have the same output on JRE11.
I briefly tested the full query logger on a JRE17 with the patch above and it
seems to be working:

-
{quote}So, if this is removed in 5.0, that also means that the places where
that method is called are not relevant anymore - as you showed its usage in
your first comment to this ticket. That means that we would need a little bit
more refactoring in 5.0 around that.
{quote}
Yes, [~isaacreath] I think we need to update the 5.0 patch to remove
{{Gossiper::hasMajorVersion3Nodes}} and any references to it.
{quote}check this, that comment in particular (1). It seems to me that unknown
version can happen in 4.0+ as well.
{quote}
We shouldn't remove this variable from {{upgradeFromVersionSupplier}} since it
will still be needed there. We just don't need the method
{{hasMajorVersion3OrUnknownNodes}} nor {{{}hasNodeWithUnknownVersion{}}}, since
these will no longer be required anywhere in 5.x.
For the 5.x patch after removing {{Gossiper::hasMajorVersion3Nodes}} we can
keep the
[upgradeFromVersionSupplier|https://github.com/apache/cassandra/blob/cassandra-5.0/src/java/org/apache/cassandra/gms/Gossiper.java#L219]
in the original configuration, where {{allHostsHaveKnownVersion}} is a local
variable within that method used
[here|https://github.com/apache/cassandra/blob/cassandra-5.0/src/java/org/apache/cassandra/gms/Gossiper.java#L253].
In summary:
- 4.0/4.1 patches: LGTM
- 5.0 patch: only remove Gossiper::hasMajorVersion3Nodes and any references to
it.
- Trunk (no change)

Fwiw I'm +1 on the patch, but let's wait a bit to see if Mick/Brandon have any
input. If you're good can you trigger ci [~smiklosovic] ? I need to setup my
circleci stuff to be able to submit, will setup this soon.

{quote}So I can see an argument for completely removing this in 5.0, but on the
other hand, there is also this "or unknown nodes" and that is still valid
question to ask. Hence, would not it be more appropriate to remove
"isUpgradingFromVersionLowerThan" and base this method just on
"hasNodeWithUnknownVersion" ?
{quote}
Upgrade from 3.x to 5.x is not supported, so this method should be removed. The
unknown version check is a pessimistic guard against a 3.x node possibly not
having its version propagated via gossip. Since upgrade from 3.x is no longer
supported on 5.x, the unknown version check should no longer exist.

[jira] [Commented] (CASSANDRA-16418) Unsafe to run nodetool cleanup during bootstrap or decommission
[ https://issues.apache.org/jira/browse/CASSANDRA-16418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17793739#comment-17793739 ] Paulo Motta commented on CASSANDRA-16418: - bq. However, from the API pov CompactionManager.performCleanup can be now called anytime - I think it was important precondition for that method - wouldn't be good to keep it there, just changing the condition to check pending ranges rather than joining status? Good point, this was overlooked during review - I suggested removing that just to cleanup but looking back I think there is value in keeping it for safety if this API is used elsewhere. Feel free to create a new ticket to add it back or piggyback in some other ticket, I'd be glad to review. To me it'd be nice that CompactionManager API is a dumb local API unaware of token ranges/membership status since it's just a local operation, but practically these concerns are mixed across the codebase so developers expect that any local API is safe from a distributed standpoint. > Unsafe to run nodetool cleanup during bootstrap or decommission > --- > > Key: CASSANDRA-16418 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16418 > Project: Cassandra > Issue Type: Bug > Components: Consistency/Bootstrap and Decommission >Reporter: James Baker >Assignee: Lindsey Zurovchak >Priority: Normal > Fix For: 4.0.8, 4.1.1, 5.0-alpha1, 5.0 > > Time Spent: 3h 20m > Remaining Estimate: 0h > > What we expected: Running a cleanup is a safe operation; the result of > running a query after a cleanup should be the same as the result of running a > query before a cleanup. > What actually happened: We ran a cleanup during a decommission.

-
{quote}Why that check in CompactionManager was removed? Was it needed for tests
to make them run? I'm afraid that the check could have been legit for
production use.
{quote}
I think that check was deemed unnecessary after a new check was added to
[StorageService.forceKeyspaceCleanup|https://github.com/apache/cassandra/blob/cassandra-4.1/src/java/org/apache/cassandra/service/StorageService.java#L3907]
to prevent starting cleanup when there are pending ranges (ie. when a node is
joining).
It's not clear to me why this latter check is not present in
[trunk|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/StorageService.java#L2524]
(while it's present in 4.0/4.1).

[jira] [Commented] (CASSANDRA-19001) Check whether the startup warnings for unknown modules represent a legit problem or cosmetic issue

Paulo Motta commented on CASSANDRA-19001:
-
{quote}A warning would not "break" it. It would inform users of the docker
image of known limitations. This buys us time to then deal with the issue
properly as we wish. (And the docker image maintainers may notice and change to
JDK anyway…)
{quote}
It would deprecate JRE support which was previously supported (ie. JRE_HOME is
mentioned
[here|https://cassandra.apache.org/doc/latest/cassandra/reference/java17.html]
and other places). If there are no hard dependencies on the JDK for core
features, I would prefer to just require it for optional features like SJK and
audit log. WDYT?
One question that arises is whether we want to continue JRE support to core
features. The benefits I can think of are smaller image size and fewer runtime
dependencies.

> The Apache Commons CLI library provides an API for parsing command line
> options with the package org.apache.commons.cli and this is already used by a
> dozen of existing Cassandra utilities including:
> {quote}SSTableMetadataViewer, StandaloneScrubber, StandaloneSplitter,
> SSTableExport, BulkLoader, and others.
> {quote}
> However, cassandra-stress is an outlier which uses its own custom classes to
> parse command line options with classes such as OptionsSimple. In addition,
> the options syntax for username, password, and others are not aligned with
> the format used by CQLSH.
> Currently, there are > 5K lines of code in 'settings' which appears to just
> process command line args.
> This suggestion is to:
>
> a) Upgrade cassandra-stress to use Apache Commons CLI (no new dependencies
> are required as this library is already used by the project)
>
> b) Align the cassandra-stress CLI options with those in CQLSH,
>
> {quote}For example, using the new syntax like CQLSH:
> {quote}
>
> cassandra-stress -username foo -password bar
> {quote}and replacing the old syntax:
> {quote}
> cassandra-stress -mode username=foo and password=bar
>
> This will simplify and unify the code base, eliminate code and reduce the
> confusion between similar named classes such as
> org.apache.cassandra.stress.settings.\{Option, OptionsMulti, OptionsSimple}
> and org.apache.commons.cli.{Option, OptionGroup, Options)
>
> Note: documentation will need to be updated as well

bq. Our quickest fix is to just fail or warn that using JRE is not recommended
(and that some features like audit logging and sjk may not work)
This would break the official Cassandra [docker image|
https://github.com/docker-library/cassandra/blob/master/5.0/Dockerfile] that is
built on top of JRE. Do we want to drop the unintended JRE support that has
been proven to work over the years on this image ?
I see the following options:
a) Make the JDK dependency optional, failing-fast if features that strictly
require it are enabled. Add testing with JRE, preferably with the official
docker image.
b) Make the JDK dependency strictly required, properly document this and work
with the official docker image maintainers to update the image to use JDK
instead.
Wdyt?

bq. As I explained, the exports/opens for Chronicle have unclear impact on
audit ligging.
Audit logging is an optional functionality as far as I understand. We can
prevent startup if audit logging is enabled and a JDK is not detected.

bq. Whole "waiting for gossip to settle" machinery is ... not ideal. Yes, it
works in most of the situations but there are edge cases when it does not, e.g.
when there are large clusters, it may happen that it may evaluate that gossip
is "settled" falsely because it took so much time to detect any changes that it
was thinking it is settled.
I'm aware waitToSettle is not reliable. Nevertheless I think having a
"best-effort" skipping of this check when 3.X nodes are detected in gossip is
valuable. This will mostly work as long as gossip with a single node was
successful, since it will get the latest known versions of the other nodes.
In the case where the gossip information is absent and there are 3.X nodes
present in the cluster, it's not a big deal - the check will just be executed
and the timeout warning above will be unnecessarily emitted.
We just don't want to skip this check when *all nodes are upgraded to 4.x* but
I don't think this would happen if waitToSettle fails.
bq. I think it would make a lot of sense to run the upgrade tests here.
Good call! Thanks

Paulo Motta commented on CASSANDRA-18968:
-
It seems like this issue was raised by [~aleksey] on CASSANDRA-13993:
{quote}As implemented currently, we are going to send PINGs potentially to
3.11/3.0 - unless we switch to gating by version, which we do sometimes.
{quote}
{quote}So I was thinking about a major upgrade bounce scenario. Think the first
ever node to upgrade to 4.0 in a cluster of 3.0 nodes - will send out pings to
every node, but receive no pongs, correct? So every node until a threshold will
have a significantly longer bounce. Do we care about this case?
{quote}
Which was replied by [~jasobrown] with:
{quote}So here's the rub: we don't necessarily know the peer's version yet. The
ping messages are sent on the large/small connections, but we're not guaranteed
that at least one round of gossip has completed wherein we would learn the
version of the peers (we're still at in the startup process).
{quote}
However I don't think this is a problem since we [wait for gossip to
settle|https://github.com/apache/cassandra/blob/7b891db36d4bcfa116ee04e3f4b3f31af798d5b2/src/java/org/apache/cassandra/service/CassandraDaemon.java#L401]
before executing this check? Can you confirm this [~brandon.williams] ?
The worst that can happen if the version of a peer is unknown is to
unnecessarily execute this check which will just fallback to the current
behavior which is not a big deal IMO - it will just make startup slightly
slower and log a warning.
Confirmed that when upgrading a cluster from 3.11 to 4.1 the following message
is print on the debug.log for all except the last node:
{noformat}
DEBUG [main] 2023-11-08 21:08:42,056 StartupClusterConnectivityChecker.java:97
- Skipping startup connectivity check as some nodes may be running Cassandra
version 3 or older which does not support connectivity checking.
{noformat}
In the last node to be upgraded the check is executed as expected:
{noformat}
INFO [main] 2023-11-08 21:35:30,387 StartupClusterConnectivityChecker.java:128
- Blocking coordination until only a single peer is DOWN in the local
datacenter, timeout=10s
INFO [main] 2023-11-08 21:35:30,453 StartupClusterConnectivityChecker.java:181
- Ensured sufficient healthy connections with [DC1] after 63 milliseconds
{noformat}
{quote}+1, I am waiting for another formal +1 and we can ship this!
{quote}
LGTM, would you like to commit this [~smiklosovic] ? If so perhaps update the
CHANGES.txt and commit message to "Skip connectivity check when upgrading from
3.X".

{quote}I do not see now the security manager warnings on startup, only on
compile.
{quote}
It's possible to reproduce this by running the official cassandra docker image
with:
{noformat}
$ docker run --name test --rm -it cassandra:5.0-alpha2
$ docker logs test | grep "WARNING:" | grep -v "Unknown"
{noformat}
But in fact it doesn't look like it's possible to disable this startup warning
according to [this
code|https://github.com/openjdk/jdk/blob/d22e368cb5dbd6812f1584c47c44b9b754a222af/src/java.base/share/classes/java/lang/System.java#L419].
I will maybe submit a openjdk ticket to allow this to be overriden when the
issue is known and is going to be addressed :)
Perhaps we could log a message before initializing the security manager on
JDK17 for users to ignore the Java ThreadAwareSecurityManager warning since
it's going to be addressed on CASSANDRA-18711 ? Not sure if that's really
needed or we can just ignore it for now :)
bq. 2) SJK cannot run sjk hh if not run with JDK.
It's possible to reproduce the SJK issue with the official 4.1 and 5.0 images,
so indeed this is not a new issue:
{noformat}
$ docker run --rm -it cassandra:latest nodetool sjk jps
$ docker run --rm -it cassandra:5.0-alpha2 nodetool sjk jps
{noformat}
But the "Uknown module" warnings show up on JRE17 even when running non-sjk
commands:
{noformat}
$ docker run --rm -it cassandra:5.0-alpha2 nodetool help
WARNING: Unknown module: jdk.attach specified to --add-exports
WARNING: Unknown module: jdk.compiler specified to --add-exports
WARNING: Unknown module: jdk.compiler specified to --add-opens
usage: nodetool [(-pwf | --password-file )]
[(-p | --port )] [(-h | --host )]
[(-pp | --print-port)] [(-pw | --password )]
[(-u | --username )] []
{noformat}
The warning above also shows up when launching the cassandra process:
{noformat}
$ docker run --name test --rm -it cassandra:5.0-alpha2
$ docker logs test | grep "WARNING: Unknown"
{noformat}
To me the JDK is an optional dependency only to support "nodetool sjk", but not
needed to run standard nodetool commands or cassandra server AFAIU (correct me
if wrong). So we could:
1) Remove the following optional lines from "jvm11-(client|server).options" and
"jvm17-(client|server).options".
{noformat}
--add-exports jdk.attach/sun.tools.attach=ALL-UNNAMED
--add-exports jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED
--add-opens jdk.compiler/com.sun.tools.javac=ALL-UNNAMED
{noformat}
2) Dynamically add these lines on cassandra-env.sh when a JDK is detected.
3) Print a friendly message when "nodetool sjk" is executed but no JDK is
present.
WDYT?

FWIW none of this is probably blocker for beta release since these are either
existing or "unfixable" issues, but it would be a nice to have.
