Failing Builds on Travis
Hi,
looking at the last builds on Travis, you'll notice that our builds are in
a pretty bad state: https://travis-ci.org/apache/flink/builds.
It seems that the last 15 builds on master all failed.
These are the errors I saw + their status:
- Deadlock during cache up/download: I asked travis and they suggested a
workaround that I'm currently testing (MALLOC_ARENA=2, in master)
- issues opening zip files: The problem there is that some jars in the
cache seem to be corrupt. I asked ASF Infra to delete all caches, they did
it already, so the problem should be resolved.
- Maven failing on the java6 builds. The issue is that Travis updated their
build environment (April update [1]), which included a version upgrade of
Maven from 3.2.5 to 3.3.1. As per Maven 3.3.1, they are not supporting Java
6 anymore [2].
It seems that travis is rolling back the April environment updates [3] so
the issue will probably disappear for a few days until they fixed their
environment update.
We can resolve the issue by two ways a) drop Java6 support, b) manually
install maven on travis (its a matter of 1-2hrs).
- The third build on travis (hadoop200-alpha) is failing due to some Flink
tests: https://travis-ci.org/apache/flink/jobs/60335907
It would be good if somebody who worked on this recently could take a
closer look.
Please let me know how you want to fix the Java6/Maven issue!
a) Drop Java 6 support for Flink
b) Use an older Maven version for now.
I'm in favor of option b) because the community recently decided to keep
Java6 support. (Fun fact: Java 7 reached its end of support lifecycle [4]
in April 2015)

Concerning the failed builds in the hadoop2.0.0-alpha profile I see a lot

in the logs. This does not look right and indicates a version conflict of
Netty. Netty 4.0 does not longer have a NioWorkerPool. I suspect that we
have multiple Netty jars in the class path. This might be related to the
other problems we're currently having with Travis.

There was a discussion ~6 months ago: http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/DISCUSS-Bump-the-minimum-Java-requirement-to-Java-7-for-Flink-td2243.html#a2249
Result was to not drop support for it. I'm not sure if anything has changed (with regards to the arguments made). You can start a new discussion if you think we should consider dropping support. In any case, let's not mix it up with the discussion here.

I looked a bit closer into the Maven issue, maybe Travis is going to
provide a compatible Maven version for the Java6 build environment:

Hi Robert,
Thanks for investigating the Travis build issues. I'm very much in favor
for dropping Java 6. It's deprecated. All major Linux distributions are
shipping at least Java 7. It's a rare use case that requires a lot of
effort for us to maintain backwards compatibility.
I don't recall the discussion but if we really decided to keep Java 6, then
I guess we have to install a custom Maven version on Travis.
Best,
Max

Bringing this up again because of a recently discovered issue:
https://issues.apache.org/jira/browse/FLINK-2235
Flink 0.9.0 will still support Java 6. Just wanted to clarify again that we
drop support for Java 6 for any further major releases. Do we have a
consensus?

Re: Failing Builds on Travis
Posted by Henry Saputra <he...@gmail.com>.
For now, the right way to use older Maven version BUT I would
recommend, similar to Spargel, make 0.9 be last release for Java6.
It is already end of life and more and more developers start flocking
to Java7 and Java8.
