-----------------------------
Summary: Operator::close() leaks Operator::out, holding reference
to buffers
Key: HIVE-5345
URL: https://issues.apache.org/jira/browse/HIVE-5345
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.13.0
Environment: Ubuntu, LXC, jdk6-x86_64
Reporter: Gopal V
Assignee: Gopal V
Attachments: out-leak.png
When processing multiple splits on the same operator pipeline, the output
collector in Operator has a held reference, which causes issues.
Operator::close() does not de-reference the OutputCollector object
Operator::out held by the object.
This means that trying to allocate space for a new OutputCollector causes an
OOM because the old one is still reachable.
