dhruba borthakur commented on HDFS-729:
---------------------------------------

Code looks good. The only question I have is that BlockManager.getCorruptInodes 
does the following:

{code}
    LinkedHashSet<INode> set = 
      new LinkedHashSet<INode>(this.maxCorruptFilesReturned*2);

{code}

Can you pl explain why the multiplication by 2 is needed?
