Examples with RegionReplicationBufferManager org.apache.hadoop.hbase.regionserver.regionreplication.RegionReplicationBufferManager used on opensource projects

Example 1 with RegionReplicationBufferManager

use of org.apache.hadoop.hbase.regionserver.regionreplication.RegionReplicationBufferManager in project hbase by apache.

the class HRegionServer method preRegistrationInitialization.

/**
 * All initialization needed before we go register with Master.<br>
 * Do bare minimum. Do bulk of initializations AFTER we've connected to the Master.<br>
 * In here we just put up the RpcServer, setup Connection, and ZooKeeper.
 */
private void preRegistrationInitialization() {
    try {
        initializeZooKeeper();
        setupClusterConnection();
        bootstrapNodeManager = new BootstrapNodeManager(asyncClusterConnection, masterAddressTracker);
        regionReplicationBufferManager = new RegionReplicationBufferManager(this);
        // Setup RPC client for master communication
        this.rpcClient = asyncClusterConnection.getRpcClient();
    } catch (Throwable t) {
        // Call stop if error or process will stick around for ever since server
        // puts up non-daemon threads.
        this.rpcServices.stop();
        abort("Initialization of RS failed.  Hence aborting RS.", t);
