Istvan Toth commented on PHOENIX-5769:
--------------------------------------
I have also removed the 6GB Xmx setting, as 7x6GB + overhead can possibly
overload the build hosts (that I recon have 16GB of RAM).
This is all just poking in the dark, but we can't get it fixed without trying
out solutions.

> 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]
