Subject Re: issure about name node HA configuration
Date Thu, 25 Jul 2013 02:38:58 GMT
Please take a look at
http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/HDFSHighAvailabilityWithQJM.html

To my understanding, nn1 and nn2 are IDs of the NameNodes - they don't have
to be the same as namenode hostnames.

Cheers
