Luke Cwik commented on BEAM-5710:
---------------------------------
This story is slowly being improved and should be better supported with the
2.8.0 release since the internal Dataflow worker image was migrated to shade
netty/tcnative internally.
Once 2.8.0 is available, do you mind testing with that and seeing if you still
have problems?
Also, if that doesn't work for you and you want to make forward progress, I
would suggest you use the specific versions defined here:

> Compatibility issues with netty 4.1.28 + tcnative 2.0.12 in beam 2.7.0 on

> Key: BEAM-5710
> URL: https://issues.apache.org/jira/browse/BEAM-5710
> Project: Beam
> Issue Type: Bug
> Components: runner-dataflow
> Affects Versions: 2.7.0
> Reporter: Steve Niemitz
> Assignee: Boyuan Zhang
> Priority: Major

> I have a beam job that runs in dataflow. The job uses BigtableIO to read
> from bigtable. Transitively, it pulls in netty 4.1.28 and netty-tcnative
> 2.0.12. This has worked fine in the past (beam 2.4.0 and 2.6.0), however in
> beam 2.7.0, the job now crashes the JVM when BigtableIO attempts to
> initialize GCP, which attempts to initialize netty-tcnative.
> I found a very similar bug reported to netty here:
> [https://github.com/netty/netty/issues/8337]
> Also, the problem seems to go away if I downgrade our tcnative version to
> 2.0.10.
>
> The error is a segfault attempting to call aprMajorVersion() in tcnative:

> it also succeeds.
