Andrey Stepachev updated HBASE-13147:
-------------------------------------
Attachment: HBASE-13147.v5.patch
Updated patch v5:
- added value to descriptor holding meta version
- now migration is a bit more intillegent, it compares versions and do minimal
updates (for 1 -> 2, for any -> 2 it will just overwrite descriptor with latest
one)
- 1 is a version anything prior to this patch, so we always write new descriptor
- 2 is a version with table family introduced (opens way to allow relatively
safe rolling upgrades)
- if master will try start with lesser version or region server will try to
open newer meta, they will fail.
> Load actual META table descriptor, don't use statically defined one.
