-----------------------------------
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:
