Subject [jira] Created: (HDFS-1545) Repeat commonly viewed statistics at the end of dfsadmin -report
Date Sat, 18 Dec 2010 01:32:01 GMT
Repeat commonly viewed statistics at the end of dfsadmin -report
----------------------------------------------------------------

                 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


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.
