stack updated HBASE-11887:
--------------------------
Attachment: 11887.txt
This seems to help. BoundedPriorityBlockingQueue has all handlers which user
CallRunners. The CallRunners hold on to Calls after they are done. All
handlers can be holding on to big ycsb puts. With this in place, I run much
longer. Heap character is completely different now. Let me dig more. This is
a branch-1/master only issue (redo of rpc priority).
> Memory retention in branch-1; millions of instances of LiteralByteString for

> Trying to test branch-1, I run out of mem pretty fast. Looking at dumps, I
> see too many instances of LiteralByteString. Seem to be 'qualifiers' and
> 'values' out of pb QualifierValue... and on up to the multi call into the
> server. Am having trouble finding how the retention is being done... Filing
> issue in meantime while work on it.
