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

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.

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

Posted by Sean Owen <so...@cloudera.com>.

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)

Posted by ch...@alpinenow.com.

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 ?

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

Posted by Sean Owen <so...@cloudera.com>.

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.

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

Posted by ch...@alpinenow.com.

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)

Posted by Sean Owen <so...@cloudera.com>.

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.

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

Posted by Chester Chen <ch...@alpinenow.com>.

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 ?
