Warning from GlobalMemoryManager

Hi all,

I am seeing a warning message when running upsert queries using Phoenix
JDBC 3.0.0-incubating version.

[Finalizer] WARN org.apache.phoenix.memory.GlobalMemoryManager - Orphaned
chunk of 6462 bytes found during finalize

Does this cause any issue? I haven't seen any one complaining. I didn't see
any issues either except it is alarming.

Thanks James. I have filed a JIRA ticket.
https://issues.apache.org/jira/browse/PHOENIX-1011 Let me know if more
information needed. Thanks for your quick response.

Please file a JIRA. Our memory manager does not actually allocate memory,
it only tracks coarse grained usage of it to prevent any OOM errors. But if
there are cases of orphaned chunks like this, then we run the risk of
disallowing memory allocations that we should otherwise allow.

Thanks,
James
