Konstantin Boudnik commented on HDFS-624:
-----------------------------------------

Hairong, as you've already realized the problem with my second patch was the 
missing modification in one of the assertions (-1 instead of 0).

Let's postpone my other modification until your patch is in. I'll open a 
separate JIRA for this. It'd be less messy this way.
