Enis Soztutar updated HBASE-6052:
---------------------------------
Release Note:
Changed .META. and ROOT tables' content to be Protobuf serialization of
HRegionInfo's instead of Writable serialization. When upgrading from 0.92 and
0.94 clusters, after master deploys META and ROOT, and before it deploys user
level tables, it does a migration for the data in the catalog files, rewriting
them in the new format.
Before upgrading, you can take an export of the catalog tables using HBASE-3271
for backup.
> Convert .META. and -ROOT- content to pb
