Hadoop DFS to report more replication metrics
---------------------------------------------
Key: HADOOP-3058
URL: https://issues.apache.org/jira/browse/HADOOP-3058
Project: Hadoop Core
Issue Type: Improvement
Components: metrics
Reporter: Marco Nicosia
Priority: Minor
Currently, the namenode and each datanode reports 'blocksreplicatedpersec.'
We'd like to be able to graph pending replications, vs number of under
replicated blocks, vs. replications per second, so that we can get a better
idea of the replication activity within the DFS.
