> Key: HDFS-1545
> URL: https://issues.apache.org/jira/browse/HDFS-1545
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: tools
> Affects Versions: 0.20.2
> Reporter: Yipeng Huang
> Priority: Trivial
> Attachments: DFSAdmin.java
>
> Original Estimate: 0.08h
> Remaining Estimate: 0.08h

> Safemode status, datanode's available, and capacity are the most commonly
> viewed statistics when running dfsadmin -report. They rightly appear first,
> followed by the statistics of individual datanodes.
> However with a large cluster, these commonly viewed statistics become
> obscured by the length of the individual datanode statistics. It is a tad
> ridiculous to have to have to grep or scroll to the top after a long list of
> nodes. For convenience, these commonly viewed statistics should be repeated
> at the end of the list.
