Subject [jira] Created: (HADOOP-415) DFSNodesStatus() should sort data nodes.
Date Wed, 02 Aug 2006 01:39:15 GMT
DFSNodesStatus() should sort data nodes.

                 Key: HADOOP-415
                 URL: http://issues.apache.org/jira/browse/HADOOP-415
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.4.0
            Reporter: Konstantin Shvachko
             Fix For: 0.5.0

HADOOP-392 introduced a new TreeMap member (datanodeMapByName) in the name node.
It is used solely for reporting the data nodes in the UI sorted by their names.
I think it is quite inefficient both time and space-wise to support an excessive
data structure just for that.
Suppose the UI will also require sorting by last heartbeat and/or by the available space....
I think DFSNodesStatus() should just sort the original datanodeMap before returning the list.
