> 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
