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.
