 Reading of the previously synced data will fail if the last block got corrupted.
---------------------------------------------------------------------------------

                 Key: HDFS-1944
                 URL: https://issues.apache.org/jira/browse/HDFS-1944
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node, hdfs client, name-node
    Affects Versions: 0.20-append
            Reporter: Uma Maheswara Rao G


For example a file can comprise 5 blcoks . In that we have written 4.5 blocks and invoked
sync. 
   Reading of this 4.5 blocks will be successful at this point of time. 
  Now when writing the remaining 0.5 block write has failed due to checksum errors, Then the
reading of the previously synced 4.5 blocks also fails.
