      New contribution Block Forensics aids investigation of missing blocks.

      Description

      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.
