Saksham Gangwar updated PHOENIX-6078:
-------------------------------------
Description:
In https://issues.apache.org/jira/browse/PHOENIX-5872
We started maintaining parent-child relationships between phoenix connections
to close those connections. But after closing those child connections we should
be removing them from the Queue which is being maintained for the same.
Here:
[https://github.com/apache/phoenix/blob/affa9e889efcc2ad7dac009a0d294b09447d281e/phoenix-core/src/main/java/org/apache/phoenix/compile/MutatingParallelIteratorFactory.java#L114]
If not removed from the queue, and if the parent connection is being reused: we
are observing the OOM issue on the container side during the mapper run.
was:
3 part approach:
1 don't count internal phoenix connections toward the client limit.
2 count internal phoenix connections toward a newly defined limit
3 track parent and child relationships between connections to close those
connections
> Remove Internal Phoenix Connections from parent LinkedQueue when closed
