Samarth Jain commented on PHOENIX-4110:
---------------------------------------
In the patch, I also added a log line to measure the amount of time we are
spending tearing down mini cluster.
For around 4961 tables, 946 seconds was spent. This was across 4 JVMs. So on an
average, each JVM had roughly 1200 tables with average tear down time of 235
seconds.
> ParallelRunListener should monitor number of tables and not number of tests

> 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.
