Example 1 with ReplicationBarrierCleaner

use of org.apache.hadoop.hbase.master.cleaner.ReplicationBarrierCleaner in project hbase by apache.

the class HMaster method startServiceThreads.

   * Start up all services. If any of these threads gets an unhandled exception
   * then they just die with a logged message.  This should be fine because
   * in general, we do not expect the master to get such unhandled exceptions
   *  as OOMEs; it should be lightly loaded. See what HRegionServer does if
   *  need to install an unexpected exception handler.
