Istvan Toth commented on PHOENIX-5769:
--------------------------------------
@dbwong . Yes it is.
Actually, those settings seem to be somewhat of a red herring, as the VM
options set there only apply to the main maven process, and everything
interesting is happening in the separate VMs started by failsafe, which have
their own VM settings.
It is also overridden by setting the property from the Jenkins script. (though
I have commented that out in Jenkins now)
The patches that I add here are mostly for testing theories about why the tests
fail, and are confirmed to be fixes for now.

> I was recently trying to commit changes to Phoenix for multiple issues and
> were asked to get clean HadoopQA runs. However, this took a huge effort as I
> had to resubmit the same patch multiple times in order to get one "clean".
> Looking at the errors the most common one were 3 "Multiple regions on
> <hostname,regions>" and 3 for apache infra issues (host shutdown), 1 for
> org.apache.hadoop.hbase.NotServingRegionException, 1 for
> SnapshotDoesNotExistException. See builds
> [https://builds.apache.org/job/PreCommit-PHOENIX-Build/] here from 3540's to
> 3560's. In addition I see multiple builds running simultaneously, limiting
> tests to running on 1 host should be configurable right?
> In addition I was recommended by [~yanxinyi] that master was less likely to
> have issues getting a clean run than 4.x. FYI [~ckulkarni]
