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.
