Istvan Toth commented on PHOENIX-6743:
--------------------------------------
Testing with explicit G1GC and a MaxGCPauseMillis=1000
For reference, HBase currently doesn't set any GC options for test.
According to
[https://docs.oracle.com/javase/8/docs/technotes/guides/vm/performance-enhancements-7.html]
, we can also remove UseCompressedOOps, as it's the deafult for heap sizes
under 32GB.
> Clean up test JVM config for Java 17
> ------------------------------------
>
> Key: PHOENIX-6743
> URL: https://issues.apache.org/jira/browse/PHOENIX-6743
> Project: Phoenix
> Issue Type: Task
> Components: core
> Affects Versions: 5.2.0, 5.1.2
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Major
>
> The Phoenix test suite fails to run on Java 17, because we're hardcoding a
> lot of VM/GC options, which are no longer even recognized by Java 17.
> We should find a set of options that work with Java 8 to Java 17.
> What makes this difficult is that the current options seem to be highly tuned
> so that the tests actually fit the limited Apache Jenkins hosts' memory, and
> simply removing all the tuning has resulted in many OOMs in the CI build in
> the past.
