[jira] [Commented] (HBASE-8015) Support for Namespaces

    [ https://issues.apache.org/jira/browse/HBASE-8015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13594917#comment-13594917 ] 

Sergey Shelukhin commented on HBASE-8015:
-----------------------------------------

+1 on making core (as opposed to cp-s I assume?)
"Given the level of autonomy namespaces will provide tenants. " what does this mean?
What kind of resource allocation will be possible, except for server groups (just examples, to understand it better)?

Then, about storing, I suggest not making it part of table name. It seems brittle, and will limit our options if we want to add features lately due to backward compat.
Also, how do we handle existing backward compat if someone already has a table name "foo.bar"?
Will root/meta have to be renamed hbase.root/hbase.meta to be in correct namespace, and how will it affect current assumptions about sorting if yes?
