{code:title=checkstyle-suppressions.xml}
+ TODO Update to use the message suppression filter once we cna update
{code}
s/cna/can
{code:title=checkstyle.xml}
+ TODO include the htrace package once we can upgrade
{code}
specifically call this out as o.a.htrace? Otherwise it's not clear since we
already disallow o.htrace later.
Can fix on commit, +1 to the patch.

Sean Busbey commented on HBASE-20332:
-
-v7
- comment out the checkstyle based checking for HTrace v3
To make use of the message attribute on the suppression we'll need to update to
[version 1.2 of the suppression
DTD|https://checkstyle.org/dtds/suppressions_1_2.dtd] and move to a version of
checkstyle that recognizes it, which is checkstyle 8.6+. We can't do that yet
because [checkstyle #5279|https://github.com/checkstyle/checkstyle/issues/5279]
is still open.
I've commented out the changes to use checkstyle to watch for htrave v3 and
left them as TODO for when we can upgrade our checkstyle version. I think we're
better off waiting for that then relying on the precommit 'hbaseanti' check
that points out lines in the patch file. I am fine with doing both (the
comments for later and the precommit patch grep) if anyone prefers.
bq. ugh. checkstyle in hte precommit run broke with a complaint that the
suppression isn't valid. but it works locally? trying to figure out the
difference.
This was a cached hbase-checkstyle jar in my environment. The reason the
checkstyle complaints weren't present was because the cached version had
neither the new rule for {{org.apache.htrace}} nor the suppression that is
causing the error in precommit.

-
-v6
- suppresses IllegalImport complaints when they involve
{{org.apache.htrace.core}}, which is the package for htrace v4 classes we use
With this change I get no new checkstyle errors locally comparing before and
after the patch as described earlier.

The reason I'm concerned about the checkstyle issues is because I know we have
some modules configured to failOnViolation=true and I don't want the build to
start failing due to these changes.{quote}
Oh sweet. I wasn't aware we had reached that point anywhere. Lemme figure
something out.

bq. I don't know of a way to flag that use of org.apache.htrace.core
specifically is fine
I was thinking about this more and I _think_ it's possible via the suppressions
file, using the {{message}} property.

Sean Busbey commented on HBASE-20332:

okay I got it.
the checkstyle output itself is not zero:
*
https://builds.apache.org/job/PreCommit-HBASE-Build/13265/artifact/patchprocess/maven-branch-checkstyle-root.txt
*
https://builds.apache.org/job/PreCommit-HBASE-Build/13265/artifact/patchprocess/maven-patch-checkstyle-root.txt
The patch version definitely shows a bunch of new warnings for htrace stuff.
The files I was looking at are the filtered versions for "checkstyle warnings
we care about"
Yetus' checkstyle plugin has an optimizations
([ref|https://github.com/apache/yetus/blob/rel/0.7.0/precommit/test-patch.d/checkstyle.sh#L213])
where it cuts the output down to just the files changed by the patch. We'll
need a way to flag that we care about all differences currently. I suspect
that'll mean either a change to yetus or keeping our own checkstyle plugin.
I'll link a jira once I figure out which. In either case I think the scope of
doing that is going to be too much to wait on.
Here's a manual diff of the two, there are 61 instances (for context, we have
16,189 existing checkstyle errors on master).

okay by default checkstyle is only run when a java file changes. My earlier

changes to java.
seems like it'd be worth at least running if {{hbase-checkstyle}} changes

Since we're removing the exclusion in a bunch of places, we need to make sure
folks don't inadvertently rely on it as an unlisted dependency. We want to make
sure that when folks reference HTrace they're referencing HTrace v4 classes and
not earlier classes. so for now we tell checkstyle to flag org.htrace and
org.apache.htrace (I don't know of a way to flag that use of
org.apache.htrace.core specifically is fine).
{quote}
In a prior version of this patch I did this as an "hbase antipattern" check
that was able to use a regex to say importing {{org.apache.htrace.core}} and
subpackages is fine. I could switch back to that if y'all prefer.

Sean Busbey commented on HBASE-20332:
-
removing hadoop from the shaded mapreduce module means removing the htrace v3
version that was included as a transitive dependency of it (since we only need
v4). Part of doing that properly required cleaning up how we handle htrace v3
coming in as a transitive of hadoop in other places. A big part of that is
removing exclusions so that we get it when Hadoop needs it for e.g. tests
(rather than, for example, expressly listing it as a compile scope dependency
of hbase-server that we don't actually need).
Since we're removing the exclusion in a bunch of places, we need to make sure
folks don't inadvertently rely on it as an unlisted dependency. We want to
make sure that when folks reference HTrace they're referencing HTrace v4
classes and not earlier classes. so for now we tell checkstyle to flag
{{org.htrace}} and {{org.apache.htrace}} (I don't know of a way to flag that
use of {{org.apache.htrace.core}} specifically is fine).

- removes the precommit check for older htrace use
- puts in a placeholder checkstyle rule that just flags all htrace use

bq. What is the dependency relationship between this issue and that one? Which
needs to get in first to make your life easier?
The only dependency is the consistency check stuff in this patch can be reused
in that one. So I guess this one?
It's not a blocking requirement though. I'm starting on that one shortly and
I'll just be working on a local branch that includes whatever the current state
of this patch is.

bq. Yes. I have another jira that's a sibling to this one to make a shaded
client artifact without hadoop as well. That one is harder because artifact
naming will likely make the 3.0 version breaking compared to earlier lines.
What is the dependency relationship between this issue and that one? Which
needs to get in first to make your life easier?

{quote}
patch you uploaded appears to actually be 4 patches, the first three of which
have been committed.
{quote}
Right, it depended on them and they weren't committed at the time. I'll rebase
and omit them on the next version.
{quote}
hbase-anti needs to print a footer link, I can't even find the results by
poking in the build output patchprocess directory. (fine to do in a follow on
if you can manually link me to the results)
{quote}
hbase-anti doesn't output anything to a log file AFAICT. it just greps the
patch file itself and throws up a vote. I can update it to output to a log and
put something in the footer, but it's going to give line numbers in the patch
file. will that be too confusing?
{quote}
htrace is retiring. there is a chance that it will go back to using org.htrace
package space if it lives on somewhere. we'll address that if it happens, i
suppose.
are we supposed to still exclude htrace from the ban transitive deps enforcer
rule? this is getting confusing.
{quote}
yeah a problem for another day I think; it's a mess for sure. I don't believe
we can ban it from the transitive dependencies so long as Hadoop needs it to
run (which is does for Hadoop < 2.8).
{quote}
bravo on commenting why we need some of the dependencies. valiant effort, i'm
sure it will be stale in two weeks, but at least it was up to date once.
{quote}
It is my honor an privilege to push the rock up the hill a few more times. ;)
{quote}
do we end up with jackson 1/2 conflict between ourselves and hadoop? looks like
you massaged it all away, maybe? do we need to make BlockCacheUtil and
ObjectModel go away?
{quote}
As far as I know this patch maintains any previous massaging of jackson 1/2
conflicts and does no new massaging of such conflicts. Maybe I have a side
effect I'm not seeing though?
I'd very much like to see the JSON needs in core modules removed, but it looked
like more work than was wise to fold into this change since I want it in 1.y
and 2.y.
{quote}
so now we build a shaded with hadoop and shaded without hadoop MR artifact?
{quote}
Yes. I have another jira that's a sibling to this one to make a shaded client
artifact without hadoop as well. That one is harder because artifact naming
will likely make the 3.0 version breaking compared to earlier lines.
{quote}
did we not have a netty.hadoop.version defined before? could've sworn I've seen
it
{quote}
We definitely had netty.hadoop.version prior to this patch. But we forgot to
include it in the "defaults when no profile is active" section that we added
for non-maven build systems.

Sean Busbey commented on HBASE-20332:
-
v3 correct unit test failures
- added a precommit check for old htrace uses
- stop excluding Hadoop's version of htrace
We've been excluding HTrace in most but not all places we reference Hadoop
artifacts, then selectively trying to add it back in since Hadoop needs it to
run. I think this was to avoid having it available at compile time to our code,
so we'd catch incorrect uses of the old version. Rather than all these
acrobatics, I've switched to a precommit check that looks for the incorrect
imports. Here's what it looks like:

I think this will do, and it avoids us having a ton of references to a
dependency we don't even want. (FWIW, Hadoop 3 and Hadoop 2.8+ rely on htrace
4, so this also avoids us manually including an htrace version that's totally
unneeded by folks with those versions)

those are definitely related failures. probably some additional missing test

Sean Busbey commented on HBASE-20332:
-
okay v2 checked out via running the commands on cluster with
{{HADOOP_CLASSPATH=/etc/hbase/conf yarn jar
hbase-shaded-mapreduce-3.0.0-SNAPSHOT.jar }}. got through
everything except VerifyReplication. had a problem with auths on the zk nodes
needed to get the peer config, but doesn't look like a shading issue.
let me run through these unit test results.

bq. But I think I have a deeper problem than that. As you mention, surely we
are using some of the hbase-server classes and having it at provided in
hbase-mapreduce would mean none of it shows up in the shaded jar. I suspect my
polluted YARN classpath is providing some of those classes. I'm going to do a
quick verification and then if necessary run through my tests again.
Yeah, tons of classes loading from my yarn environment (from hbase-client,
hbase-common, hbase-server, etc) :(
back in a while once I clean it out and run through things again.

-
one additional note on the "especially #1 and #2 above", the current text in
the section on mapreduce classpaths expressly tell folks to do what #1 and #2
say to do wrt how MR jobs should be invoked in the Hadoop framework, they just
leave out the newer "yarn job" in favor of the older "hadoop job" invocation.
If time, I'll try to see when "yarn job" got added and make a note of it.

{quote}
How's this work relate to what we have in guide since time immemorial?
http://hbase.apache.org/book.html#hbase.mapreduce.classpath Especially your #1
and #2 above.
{quote}
Leaving aside the {{hadoop jar}} vs {{yarn jar}} hadoop details, I think those
instructions just tell you how to submit stuff using the non-shaded mr stuff.
Since we have a goal of "push folks to the shaded bits" then probably I'll need
to rewrite that section once I'm convinced the MR shaded jar works. The
essentials still look the same, {{HADOOP_CLASSPATH}} and {{-libjars}} just need
to point at the shaded mr jar instead.
(also the ref guide is still naming full qualified classnames instead of short
name? ugh.)
{quote}
The workarounds are for the doubled mention of the shaded hbase mr jar?
Skimmed the patch.
Is this right?
199 hbase-server
200 provided
How is hbase-server provided at runtime if not in the hbase-shaded-mapreduce
jar?
{quote}
The workaround of {{HADOOP_USER_CLASSPATH_FIRST}} was for my attempt to us
{{exportsnapshot}} failing because my local YARN install has its own set of
HBase jars that it is putting into my application's classpath.
But I think I have a deeper problem than that. As you mention, surely we are
using _some_ of the hbase-server classes and having it at provided in
hbase-mapreduce would mean none of it shows up in the shaded jar. I suspect my
polluted YARN classpath is providing some of those classes. I'm going to do a
quick verification and then if necessary run through my tests again.
{quote}
Say more why the new module hbase-shaded-with-hadoop-check-invariants?
{quote}
The way the "check invariants" modules work is they run against the set of
dependencies listed for the module. To date I've tried not to have logic in the
jar verification script about specific jars to check. Since we need to treat
the contents of {{hbase-shaded-client}} different from
{{hbase-shaded-mapreduce}}, I added the flag to the script for "can Hadoop be
in here?" but I need a way to determine if that flag is passed to the
invocation. If we want to be able to just do accounting of the jars to check
via dependencies to the check-invariants pom(s), then we need two modules so
that one can pass the flag and the other not.
An alternative would be to keep a single check invariants module, but to stop
automatically enumerating the dependencies to pass to the jar checking
invocation and instead build two executions of the jar checking script where we
list each jar it should check. We could maybe do this in beanshell and just do
a whitelist regex for "can have hadoop classes".

That maven-shade-plugin bug sounds like something that would cause the burning
of hours of WTF!
bq. i.e. remove the top level listing of it as a dependency
Agree. Was privvy to a half-hearted attempt in the past. Need to come back to
it.
The workarounds are for the doubled mention of the shaded hbase mr jar?
Skimmed the patch.
Is this right?
199 hbase-server
200 provided
How is hbase-server provided at runtime if not in the hbase-shaded-mapreduce
jar?
Nice additions in ensure-jars-have-correct-contents.sh
s/pacakge/package/
s/ and and / and /
Say more why the new module hbase-shaded-with-hadoop-check-invariants?

yay! workaround via {{HADOOP_USER_CLASSPATH_FIRST=true}} looks good.

okay the export snapshot failure is a polluted classpath in my YARN
installation. I would like to confirm I can work around it, if only so that I
can check the actual command, but I think that command is probably fine.

# Use with a MR job that's not built-in
# Make sure we're not doing something with the Configuration object that's

Sean Busbey commented on HBASE-20332:

Okay I've gone through most of the built in MR jobs:
{code}
An example program must be given as the first argument.
Valid program names are:
CellCounter: Count cells in HBase table.
WALPlayer: Replay WAL files.
completebulkload: Complete a bulk data load.
copytable: Export a table from local cluster to peer cluster.
export: Write table data to HDFS.
exportsnapshot: Export the specific snapshot to a given FileSystem.
import: Import data written by Export.
importtsv: Import data in TSV format.
rowcounter: Count rows in HBase table.
verifyrep: Compare data from tables in two different clusters. It doesn't
work for incrementColumnValues'd cells since timestamp is changed after
appending to WAL.
{code}
These all worked fine (see note at end though):
* CellCounter
* copytable (with and without bulkload)
* export
* import
* importtsv (with and without bulkload)
* completebulkload
* rowcounter
I don't have stuff set up ATM to do {{WALPlayer}} or {{verifyrep}}.
When running {{exportsnapshot}} I got the following failure, which I haven't
dug into yet:

those shellcheck and whitespace things should be easy enough to fix. I'll take

Sean Busbey commented on HBASE-20332:
-
to test out, first do a local install so you can get what the pom/jar will look
like:
{code}
mvn -Psite-install-step -Prelease install
{code}
Now you can look in your local maven repo for the jar(s) and the poms that a
client will get (default user repo listed in this example):
{code}
mvn dependency:list -f
~/.m2/repository/org/apache/hbase/hbase-shaded-mapreduce/3.0.0-SNAPSHOT/hbase-shaded-mapreduce-3.0.0-SNAPSHOT.pom
mvn dependency:tree -f
~/.m2/repository/org/apache/hbase/hbase-shaded-mapreduce/3.0.0-SNAPSHOT/hbase-shaded-mapreduce-3.0.0-SNAPSHOT.pom
{code}
junit shows up because of our root parent pom giving it as a dependency. I
tried a few things to get rid of it but nothing worked. I think we need to fix
that generally (i.e. remove the top level listing of it as a dependency) rather
than try to do it here.

Sean Busbey commented on HBASE-20332:
-
re #1, you currently can't use our shaded mapreduce jar to submit MR
applications directly without the use of the {{hadoop jar}} / {{yarn jar}}
commands, because we need some Hadoop common bits for dealing with the local
filesystem. so if we want a standalone jar for e.g. submitting MR jobs from a
node that has no Hadoop installation, that's a different pile of work (and I'd
argue a less common case that we should handle after making sure we have a
simple "easy" path)
