Tool to give the block location and to check if the block at a given datanode
is corrupt or not
-----------------------------------------------------------------------------------------------
Key: HADOOP-4761
URL: https://issues.apache.org/jira/browse/HADOOP-4761
Project: Hadoop Core
Issue Type: New Feature
Components: dfs
Reporter: Ramya R
Priority: Minor
Fix For: 0.20.0
It would be useful if we could have a command line tool which would list out
the location of all the replicas of a block given a block-id/filename. Also, an
utility to check if the block at a given datanode is corrupt or not would be of
great help in managing the cluster.
