Allen Wittenauer resolved HDFS-356.
-----------------------------------

    Resolution: Fixed

I'm going to close out given that a lot/most/all of this information is available via metrics2.

>                 Key: HDFS-356
>                 URL: https://issues.apache.org/jira/browse/HDFS-356
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>            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, ...)
