Subject Updating from 0.90.2 to 0.94
Date Tue, 26 Feb 2013 07:33:15 GMT
hi all, 
I am updating production cluster from 0.90.2 to 0.94 .  My table's size is about 20TB+ .
Scheduled update includes upgrading both hbase,hadoop version,
 and I am also changing user with which I  start up both hadoop and hbase cluster  from user
"A" to user "B".

It's production environment , so I wanted know what steps I should not miss regarding this
Table is kinda big and I don't have backup cluster to backup my data. 
I wanted to know will there be a data loss scenario if I rollback after having failed to upgrade.

Best Regards
Yusup Ashrap
