Virag Kothari updated HBASE-12233:
----------------------------------
Attachment: HBASE-12233.patch
Attached is the initial patch for review (master branch)
Primary changes:
- meta-region-server znode has additional fields for backward compatibility
1) isRoot - For branch-1/0.98 whether this znode is holding root or meta
location
2) rootSchema - If we are changing the root comparator/schema
-Root has its own WAL
- MetaTableLocator and MetaTableAccessor has added/changed few stateless
utility methods (I plan to
remain this to CatalogTableLocator and CatalogTableAccessor. Didn't refactor in
the first patch so that actual changes
can be easily reviewed)
-Public client API's changed
1) HRegionInfo adds #isRootRegion()
2) Registry changes API from #getMetaRegionLocation to #getRootRegionLocation
-Few assignment related changes (Separate SSH for root)
> Bring back root table
