Hi,
When I restarted a cluster with 1.1 , I found that hbase:meta region
(written to by the previously deployed 2.0) couldn't be opened:

When user does rolling upgrade from 1.1 to 2.0, the above may cause problem
if hbase:meta region is updated by server running 2.0 but later assigned to
a region server which still runs 1.1 (due to crash of the server running
2.0, e.g.)
I want to get community feedback on the severity of this issue.
Thanks
