Subject Re: How to fail the Name Node or how to crash the Name Node for testing Purpose.
Date Wed, 19 Jun 2013 07:04:26 GMT

If we power of the Host then the secondary name node also goes down. I want
to simulate the name node failure and what to do some recovery. Every thing
is part of the testing the name node recovery.
