-----------------------------------------------------------------------------
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.
