Re: [PROPOSAL] Prepare Beam 2.7.0 release

I attempted to cut the 2.7.0 RC1 today, but encountered an issue where the
JVM consistently segfaulted at
the :beam-sdks-java-io-hadoop-input-format:test task.  I will investigate
further tomorrow.  Let me know if this anyone knows of this issue and has
any insight.

Re: [PROPOSAL] Prepare Beam 2.7.0 release

Making steady progress, but there is an issue compiling with Protobuf for
Python which I am investigating right now.

Re: [PROPOSAL] Prepare Beam 2.7.0 release

Posted by Charles Chen <cc...@google.com>.
Thanks!  I talked to Boyuan who indicated that this may be an issue
specific to the JVM version I am running, since she saw a similar issue
while performing the 2.5.0 release.  Next step on my end is to set up
another machine with a different JVM version to run these steps.

Re: [PROPOSAL] Prepare Beam 2.7.0 release

Posted by Alexey Romanenko <ar...@gmail.com>.
Charles,
Does it happen when you run this task separately or as a part of the whole project build? I run it independently and don’t see any issues on my side. Also, I don’t remember that it failed on Jenkins recently. So, probably this segfault is not related to exactly this task.
