Apache Drill 0.7 and MR table performance and connectivity

There are 2 ways to connect a table created by mapr table.

1 select * from dfs.`/user/mapr/mytable`

2 select * from hbase.`/user/mapr/mytable`

**I**

I am wondering is there any different regarding performance?

**II**

There is requirement on HBASE 0.94 for Drill 0.7, if I always access mapr table in the 1 way, does this mean I can install another version of HBase, such as 0.98 ???


**III**


Is Drill now ready for production usage ? This really concerns me. Do we have successful practice now for the production usage ?
