[~ljain] The change looks good, I am going to take a week to think through this and review
with the rest of the team before I commit this. The reason is that command provides the ability
to destroy data ( and rightfully so)
 [~msingh], [~nandakumar131],[~elek] and [~xyao] Please take a look at the patch when you
have a chance. I want to commit this only after I get perspectives from others too. Thanks
for your time and consideration.

> Once a datanode is restarted its open containers should be formatted. Only the open containers
whose pipeline has a replication factor of three will need to be formatted. The format command
is sent by SCM to the datanode after the corresponding containers have been successfully replicated.
