Short -metasave option
-----------------------
Key: HADOOP-2607
URL: https://issues.apache.org/jira/browse/HADOOP-2607
Project: Hadoop
Issue Type: Improvement
Components: dfs
Affects Versions: 0.14.3
Reporter: Koji Noguchi
Priority: Minor
In Hadoop-2606 bug, dfsadmin -metasave was quite useful in digging into
namenode's state.
However, the log it created was over 100MBytes for each call.
It would be nice to have a lighter version of -metasave that only prints out
the total counts.
(blocks waiting for replication, being replicated, waiting for deletion, ...)
