That's correct for the 1.5 branch, right? this doesn't mean that the
next RC would have this value. You choose the release version during
the release process.

Sorry, I am still not follow. I assume the release would build from 1.5.0 
before moving to 1.5.1. Are you saying the 1.5.0 rc3 could build from 1.5.1 
snapshot during release ? Or 1.5.0 rc3 would build from the last commit of 
1.5.0 (before changing to 1.5.1 snapshot) ?

Re: [VOTE] Release Apache Spark 1.5.0 (RC2)

2015-09-01 Thread Sean Owen

The head of branch 1.5 will always be a "1.5.x-SNAPSHOT" version. Yeah
technically you would expect it to be 1.5.0-SNAPSHOT until 1.5.0 is
released. In practice I think it's simpler to follow the defaults of
the Maven release plugin, which will set this to 1.5.1-SNAPSHOT after
any 1.5.0-rc is released. It doesn't affect later RCs. This has
nothing to do with what commits go into 1.5.0; it's an ignorable
detail of the version in POMs in the source tree, which don't mean
much anyway as the source tree itself is not a released version.

Thanks for the explanation. Since 1.5.0 rc3 is not yet released, I assume it 
would cut from 1.5 branch, doesn't that bring 1.5.1 snapshot code ? 

The reason I am asking these questions is that I would like to know If I want 
build 1.5.0  myself, which commit should I use ?

Any 1.5 RC comes from the latest state of the 1.5 branch at some point
in time. The next RC will be cut from whatever the latest commit is.
You can see the tags in git for the specific commits for each RC.
There's no such thing as "1.5.1 SNAPSHOT" commits, just commits to
branch 1.5. I would ignore the "SNAPSHOT" version for your purpose.

You can always build from the exact commit that an RC did by looking
at tags. There is no 1.5.0 yet so you can't build that, but once it's
released, you would be able to find its tag as well. You can always
build the latest 1.5.x branch by building from HEAD of that branch.

Re: [VOTE] Release Apache Spark 1.5.0 (RC2)

2015-08-31 Thread Reynold Xin

I'm going to -1 the release myself since the issue @yhuai identified is
pretty serious. It basically OOMs the driver for reading any files with a
large number of partitions. Looks like the patch for that has already been
merged.

I'm going to cut rc3 momentarily.

Seems that Github branch-1.5 already changing the version to
1.5.1-SNAPSHOT,

I am a bit confused are we still on 1.5.0 RC3 or we are in 1.5.1 ?

 ===
 If you are a Spark user, you can help us test this release by taking an
 existing Spark workload and running on this release candidate, then
 reporting any regressions.


 
 What justifies a -1 vote for this release?
 
 This vote is happening towards the end of the 1.5 QA period, so -1 votes
 should only occur for significant regressions from 1.4. Bugs already
 present in 1.4, minor regressions, or bugs related to new features will not
 block this release.


 ===
 What should happen to JIRA tickets still targeting 1.5.0?
 ===
 1. It is OK for documentation patches to target 1.5.0 and still go into
 branch-1.5, since documentations will be packaged separately from the
 release.
 2. New features for non-alpha-modules should target 1.6+.
 3. Non-blocker bug fixes should target 1.5.1 or 1.6.0, or drop the target
 version.

Marcelo,

Thanks for replying -- after looking at my test again, I misinterpreted
another issue I'm seeing which is unrelated (note I'm not using a pre-built
binary, rather had to build my own with Yarn/Hive support, as I want to use
it on an older cluster (CDH5.1.0)).

I can start up a pyspark app on YARN, so I don't want to block this. +1

Best,
Jonathan

Hi Jonathan,

Can you be more specific about what problem you're running into?

SPARK-6869 fixed the issue of pyspark vs. assembly jar by shipping the
pyspark archives separately to YARN. With that fix in place, pyspark
doesn't need to get anything from the Spark assembly, so it has no
problems running on YARN. I just downloaded
spark-1.5.0-bin-hadoop2.6.tgz and tried that out, and pyspark works
fine on YARN for me.

It seems like this JIRA https://issues.apache.org/jira/browse/SPARK-7733
added a requirement for Java 7 in the build process. Due to some quirks
with the Java archive format changes between Java 6 and 7, using PySpark
with a YARN uberjar seems to break when compiled with anything after
Java 6
(see https://issues.apache.org/jira/browse/SPARK-1920 for reference).

Found a problem on reading partitioned table. Right now, we may create a
SQL project/filter operator for every partition. When we have thousands of
partitions, there will be a huge number of SQLMetrics (accumulators), which
causes high memory pressure to the driver and then takes down the cluster
(long GC time causes different kinds of timeouts).

https://issues.apache.org/jira/browse/SPARK-10339

Will have a fix soon.

The binary archives seems to be having some issues, which seems consistent
on few of the different ones (different versions of hadoop) that I tried.

Are you just submitting from Windows or are you also running YARN on Windows?

If the former, I think the only fix that would be needed is this line
(from that same patch):
https://github.com/apache/spark/blob/master/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala#L434

I don't believe YARN running on Windows worked at all before that
patch (regardless of that individual issue). I'll leave it to Reynold
whether Windows support is critical enough to warrant a new rc.

+1. I tested the without hadoop binary package and ran our internal
tests on it with dynamic allocation both on and off.

The Windows issue Sen raised could be considered a regression /

 ===
 How can I help test this release?
 ===
 If you are a Spark user, you can help us test this release by taking an
 existing Spark workload and running on this release candidate, then
 reporting any regressions.


 
 What justifies a -1 vote for this release?
 
 This vote is happening towards the end of the 1.5 QA period, so -1 votes
 should only occur for significant regressions from 1.4. Bugs already
 present in 1.4, minor regressions, or bugs related to new features will not
 block this release.


 ===
 What should happen to JIRA tickets still targeting 1.5.0?
 ===
 1. It is OK for documentation patches to target 1.5.0 and still go into
 branch-1.5, since documentations will be packaged separately from the
 release.
 2. New features for non-alpha-modules should target 1.6+.
 3. Non-blocker bug fixes should target 1.5.1 or 1.6.0, or drop the target
 version.

Marcelo - please submit a patch anyway. If we don't include it in this
release, it will go into 1.5.1.

 Looks like Josh just found a blocker, so maybe we can squeeze this in?

I was looking for a version of this release based on Hadoop 2.2.  Is there
some reason there isn't one, especially since 2.2.0 is described as the
default Hadoop version?

Re: [VOTE] Release Apache Spark 1.5.0 (RC2)

2015-08-26 Thread Sean Owen

My quick take: no blockers at this point, except for one potential
issue. Still some 'critical' bugs worth a look. The release seems to
pass tests but i get a lot of spurious failures; it took about 16
hours of running tests to get everything to pass at least once.


Current score: 56 issues targeted at 1.5.0, of which 14 bugs, of which
no blockers and 8 critical.

This one might be a blocker as it seems to mean that SBT + Scala 2.11
does not compile:
https://issues.apache.org/jira/browse/SPARK-10227

pretty simple issue, but weigh in on the PR:

The Scala 2.11 issue should be fixed, but doesn't need to be a blocker,
since Maven builds fine. The sbt build is more aggressive to make sure we
