Examples with ReplicationLoad org.apache.hadoop.hbase.replication.regionserver.ReplicationLoad used on opensource projects

Example 1 with ReplicationLoad

use of org.apache.hadoop.hbase.replication.regionserver.ReplicationLoad in project hbase by apache.

the class HRegionServer method buildServerLoad.

    // We're getting the MetricsRegionServerWrapper here because the wrapper computes requests
    // per second, and other metrics  As long as metrics are part of ServerLoad it's best to use
    // the wrapper to compute those numbers in one place.
    // In the long term most of these should be moved off of ServerLoad and the heart beat.
    // Instead they should be stored in an HBase table so that external visibility into HBase is
    // improved; Additionally the load balancer will be able to take advantage of a more complete
    // history.
