Subject CDH412/Hadoop 2.0.3 Upgrade instructions
Date Mon, 21 Jan 2013 23:05:36 GMT
I am trying to upgrade a Hadoop Cluster with 0.20.X and MRv1 to a hadoop 
Cluster with CDH412 with HA+QJM+YARN (aka Hadoop 2.0.3) without any  
data loss and minimal down time. The documentation on cloudera site iis 
OK, but very confusing. BTW I do not plan on using Cloudera manager. Has 
anyone attempted a clean upgrade using hadoop native commands?

Appreciate a quick reply.
