Chia-Ping Tsai created HBASE-17943:
--------------------------------------

             Summary: The in-memory flush size is different for each CompactingMemStore located
in the same region 
                 Key: HBASE-17943
                 URL: https://issues.apache.org/jira/browse/HBASE-17943
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 2.0.0
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai
             Fix For: 2.0.0

  private void initInmemoryFlushSize(Configuration conf) {
    long memstoreFlushSize = getRegionServices().getMemstoreFlushSize();
    int numStores = getRegionServices().getNumStores();
    if (numStores <= 1) {
      // Family number might also be zero in some of our unit test case
      numStores = 1;
    }
    inmemoryFlushSize = memstoreFlushSize / numStores;
{noformat}
We initialize each store in parallel, so the return value from getNumStores() may be different
for each CompactingMemStore.
