Subject [jira] [Created] (PHOENIX-5311) Integration tests leak tables when running on distributed cluster

------------------------------------

             Summary: Integration tests leak tables when running on distributed cluster
                 Key: PHOENIX-5311
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5311
             Project: Phoenix
          Issue Type: Bug
            Reporter: István Tóth


When integration test suite is run via End2EndTestDriver on a distributed cluster, most tests
do not clean up their tables, leaving thousands of tables on the cluster, and exhausting RegionServer
memory.

There are actually three problems:
 * The BaseTest.freeResourcesIfBeyondThreshold() method is called after most tests, and it
restarts the MiniCluster, thus freeing resources, but it has no effect when running on a distributed
cluster.
 * The TestDriver sets phoenix.schema.dropMetaData to false by default, so even if the Phoenix
tables are dropped, the HBASE tables are not, so the table leak remains. 
 * The phoenix.schema.dropMetaData setting cannot be easily overridden because of PHOENIX-5310
