Vladimir Rodionov commented on HBASE-12023:
-------------------------------------------
I think we need a separate master JIRA to track al *too many objects* - type of
issues. They are all over the HBase source code. We need to post a memory
conserving rules somewhere in HBase book and not to accept patches which do not
follow this guideline.
> HRegion.applyFamilyMapToMemstore creates too many iterator objects.
