Subject [jira] Created: (HADOOP-3323) Name node should notify administrator if when struggling with replication

Name node should notify administrator if when struggling with replication
-------------------------------------------------------------------------

                 Key: HADOOP-3323
                 URL: https://issues.apache.org/jira/browse/HADOOP-3323
             Project: Hadoop Core
          Issue Type: Improvement
          Components: dfs
            Reporter: Robert Chansler


Name node performance suffers if either the replication queue is to big, or the avail space
at data nodes is too small. In either case, the administrator should be notified.

If the situation is really desperate, the name node perhaps should enter safe mode.
