[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=14142193#comment-14142193 ] 

Prasanna commented on HBASE-8015:
---------------------------------

Do different namespaces for the same table name create different tables directories in hdfs and are maintained in different region files? 

How does this affect namenode memory if I want to have one namespace per user and I have a million users registered to my system. Will this scale?

I would like namespace to be totally logical separation all sharing the same region file. Is this case?
Thank you for any responses.
