[IHBASE] Idx memory allocation fix

                 Key: HBASE-2206
                 URL: https://issues.apache.org/jira/browse/HBASE-2206
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack
             Fix For: 0.20.4

 Idx memory allocation fix
  - Includes a modification to core - MemStore was added with a numKeyValues query
  - It optimizes the number of memory allocation required to rebuild the index.  This is a
major fix - it reduces the heap fragmentation and helped postpone/fix (not yet sure which
of those) the region server crashing due to those long GC periods on a write-intensive setup
