As per the docs, it looks like painless to upgrade from 0.20.3 to 0.90
(only need to run upgrade script if upgrading to 0.92).
Anyone has experience in upgrading from 0.20 to 0.90 or something similar
with major upgrade ? Do we need to upgrade hadoop (0.20.1) as well ? or can
0.20.1 work with 0.90 hbase ?
Trying to minimize the impact with one upgrade at a time.. any help
Thanks in advance
