            Reporter: stack
             Fix For: 2.0.1


Add a note to upgrade section that user has to undo dependency on prefix-tree before they upgrade to hbase2.

To get over prefix-encoding, you need to do the below before upgrade (From [~appy])

1. Change the encoding to something other than PREFIX_TREE and which is supported by hbase2
2. Major ompact the tables which were changed so they are rewritten into the new encoding.
3. Retry upgrade
