Subject [jira] Created: (HADOOP-1946) du should be not called on every heartbeat
Date Tue, 25 Sep 2007 22:59:50 GMT
du should be not called on every heartbeat

                 Key: HADOOP-1946
                 URL: https://issues.apache.org/jira/browse/HADOOP-1946
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.15.0
            Reporter: Konstantin Shvachko
             Fix For: 0.15.0

Data-nodes run very slow. The reason is that du is executed on each and every heartbeat.
Looks like the condition in DU.getUsed(), which triggers the refresh of cached values, should
be reversed.
