The wait on compaction because "Too many store files" holds up all flushing
---------------------------------------------------------------------------

                 Key: HBASE-2087
                 URL: https://issues.apache.org/jira/browse/HBASE-2087
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack


The method MemStoreFlusher#checkStoreFileCount is called from flushRegion.  flushRegion is
called by MemStoreFlusher#run thread.  If the checkStoreFileCount finds too many store files,
it'll stick around waiting on a compaction to happen.  While its hanging, the MemStoreFlusher#run
is held up.  No other region can flush.  Meantime WALs will be rolling and memory will be
accumulating writes.
