List of computeDatanodeWork() Examples

Examples of computeDatanodeWork()

org.apache.hadoop.hdfs.server.namenode.FSNamesystem.computeDatanodeWork()
Compute block replication and block invalidation work that can be scheduled on data-nodes. The datanode will be informed of this work at the next heartbeat. @return number of blocks scheduled for replication or removal.
