Examples of org.apache.hadoop.hbase.master.BulkAssigner

org.apache.hadoop.hbase.master.BulkAssigner
Base class used bulk assigning and unassigning regions. Encapsulates a fixed size thread pool of executors to run assignment/unassignment. Implement {@link #populatePool(java.util.concurrent.ExecutorService)} and{@link #waitUntilDone(long)}. The default implementation of the {@link #getUncaughtExceptionHandler()} is to abort the hostingServer.

    Map<ServerName, List<HRegionInfo>> bulkPlan =
        this.assignmentManager.getBalancer().retainAssignment(regionsToAssign, onlineServers);
    LOG.info("Bulk assigning " + regionsCount + " region(s) across " + bulkPlan.size()
      + " server(s), retainAssignment=true");
    
    BulkAssigner ba = new GeneralBulkAssigner(this.server, bulkPlan, this.assignmentManager, true);
    try {
      if (ba.bulkAssign()) {
        done = true;
      }
    } catch (InterruptedException e) {
      LOG.warn("Enable operation was interrupted when enabling table '"
        + this.tableName + "'");
