Liu Shaohui commented on HBASE-10692:
-------------------------------------

[~mbertozzi]
The patch just make the multi table-Map job support the security HBase cluster. 
And those tables should be at the same cluster, so we only see a single conf 
object for the mappers.

I am not sure if we should support multiple tables from the different clusters. 
It's just a discussion.
If it is needed,  i will open another issue to implement it.
