    Description

      Compactions read a lot of data into the heap. Prior to HBASE-1058 or successor issues, it was possible to stack up hundreds if not thousands of flushes in a store. Eventually when compaction is possible, no HRS has enough heap to commit for the compaction process and all OOME as the region in question is (re)deployed. HBASE-1058 is not the ideal solution.This issue suggests creating a memory efficient compaction process which can scale.
