DFS client blocked for a long time reading blocks of a file on the JobTracker
-----------------------------------------------------------------------------

                 Key: HADOOP-5286
                 URL: https://issues.apache.org/jira/browse/HADOOP-5286
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.20.0
            Reporter: Hemanth Yamijala


On a large cluster, we've observed that DFS client was blocked on reading a block of a file for almost 1 and half hours. The file was being read by the JobTracker of the cluster, and was a split file of a job. On the NameNode logs, we observed that the block had a message as follows:

Inconsistent size for block blk_2044238107768440002_840946 reported from <ip>:<port> current size is 195072 reported size is 1318567

Details follow.
