             Summary: TestQueriesOnLargeFile leaks memory with 16M limit
                 Key: DRILL-3063
                 URL: https://issues.apache.org/jira/browse/DRILL-3063
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
            Reporter: Chris Westin
            Assignee: Chris Westin
             Fix For: 1.0.0


I ran the TestQueriesOnLargeFile unit test with a limited memory environment, limiting direct memory to 16M. At the end of the test, the shutdown hook reports a memory leak.

Here is the test launch configuration:
-Xms512m
-Xmx3g
-Ddrill.exec.http.enabled=false
-Ddrill.exec.sys.store.provider.local.write=false
-Dorg.apache.drill.exec.server.Drillbit.system_options="org.apache.drill.exec.compile.ClassTransformer.scalar_replacement=on"
-XX:MaxPermSize=256M -XX:MaxDirectMemorySize=3072M
-XX:+CMSClassUnloadingEnabled -ea
-Ddrill.exec.memory.top.max=16777216

Here's what I see at the end:
	at org.apache.drill.exec.server.Drillbit$ShutdownThread.run(Drillbit.java:333)
Caused by: java.lang.IllegalStateException: Failure while closing accountor.  Expected private and shared pools to be set to initial values.  However, one or more were not.  Stats are
