Istvan Toth commented on HBASE-28135:
-------------------------------------
We aready set -Xmx, but the NewSize and OldSize parameters are computed from
-Xms, which we do not set yet.
> Specify -Xms for tests

> Key: HBASE-28135
> URL: https://issues.apache.org/jira/browse/HBASE-28135
> Project: HBase
> Issue Type: Improvement
> Components: test
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Major
>
> The default -Xms value is JVM dependent, but the host memory size is usually
> included in the calculation.
> -Xms in turn is used to calculate some GC parameters, for example NewSize and
> OldSize, which affect the behaviour of tests.
> As the memory consumption on the tests is not dependent on the host VM size,
> we could set -Xms for the tests explictly, and enjoy more consistent test
> results.
