Ramkumar Vadali updated HDFS-1472:
----------------------------------

    Attachment: HDFS-1472.patch

Adds a constructor DFSck(Configuration, PrintStream). This is better than 
modifying System.out.

> Refactor DFSck to allow programmatic access to output

> DFSck prints the list of corrupt files to stdout. This jira proposes that it 
> write to a PrintStream object that is passed to the constructor. This will 
> allow components like RAID to programmatically get a list of corrupt files.
