Colin Patrick McCabe commented on HDFS-7326:
--------------------------------------------

Hi [~vijaysbhat], this is good.  Thanks for taking a look at this.

{code}
| -block <block-file>    | Absolute path for the block file on the local file
|                        | system for the data node.
{code}
Perhaps write "optional paramater that..." to make it clear that this argument 
isn't required.

{code}
| [-retries <num-retries>]      | The default number of retries is 1.
{code}
Perhaps we should mention that this is the number of times we'll retry the 
recoverLease call here as well.
