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