 StoreScanner calls Configuration for Boolean Check on each initialization
 -

 Key: HBASE-12912
 URL: https://issues.apache.org/jira/browse/HBASE-12912
 Project: HBase
  Issue Type: Bug
Reporter: John Leach
Assignee: John Leach
 Fix For: 1.0.0, 2.0.0, 0.98.10, 1.1.0

 Attachments: StoreScannerStall.tiff

   Original Estimate: 1h
  Remaining Estimate: 1h

 There is a clear CPU drain and iterator creation when creating store scanners 
 under high load.  Splice was running a TPCC test of our database and we are 
 seeing object creation and CPU waste on the boolean check
 Code Snippet...
 if (store != null  ((HStore)store).getHRegion() != null
  store.getStorefilesCount()  1) {
   RegionServerServices rsService = 
 ((HStore)store).getHRegion().getRegionServerServices();
   if (rsService == null || !rsService.getConfiguration().getBoolean(
 STORESCANNER_PARALLEL_SEEK_ENABLE, false)) return;
   isParallelSeekEnabled = true;
   executor = rsService.getExecutorService();
 }
 Will attach profile...
