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.
> Short -metasave option

> 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, ...)
