[jira] [Comment Edited] (PHOENIX-4110) ParallelRunListener should monitor number of tables and not number of tests

    [ https://issues.apache.org/jira/browse/PHOENIX-4110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16138885#comment-16138885 ]

Nice analysis, [~samarthjain]! Alternate idea: how about we just get rid of PhoenixTestDriver and the modifications we do to HBase Configuration in BaseTest? Then we can just turn on class-level parallelization (FYI, the prior issue with endless logging to stdout has been fixed). This has the advantages of our tests better mimicing how they'll run on a real cluster.

To do this, you'd just need to uncomment these lines in the top level pom.xml (and change methods to classes, at least as an initial test):
{code}
                <parallel>classes</parallel>
                <threadCount>20</threadCount>
{code}
and then set numForkedIT to 1 as we shouldn't need multiple JVMs.

We can play around with the best value for threadCount.

We also need to convert all ClientManagedTimeTests due to PHOENIX-4096

> ParallelRunListener today monitors the number of tests that have been run to determine when mini cluster should be shut down. This helps prevent our test JVM forks running in OOM. A better heuristic would be to instead check the number of tables that were created by tests. This way when a particular test class has created lots of tables, we can shut down the mini cluster sooner.
