Istvan Toth commented on PHOENIX-5769:
--------------------------------------
OK, so it looks like the build hosts have 48GB, but have up two executors
running on them, so we can count on having ~24GB of memory available. (provided
that the other job doesn't hog the memory, though that does not seem to be the
case, we fail as much when we are the only job, as we do when we are sharing
the host)
I have added lscpu to the startup script, because I couldn't figure out how
many and how fast cores we can work with.

> 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]
