                 Key: HDFS-567
                 URL: https://issues.apache.org/jira/browse/HDFS-567
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: tools
            Reporter: Bill Zeller
            Assignee: Bill Zeller
            Priority: Minor
             Fix For: 0.21.0


Includes a java program to query the namenode for corrupt replica information at some interval. If a corrupt replica is found, a map reduce job is launched that will search (supplied) log files for one or more block ids. The mapred job can be used independently of the java client program and can also be used for arbitrary text searches.
