Subject Re: Adding features to HBase Input Operators in Malhar-contrib
Date Tue, 22 Dec 2015 05:38:33 GMT
+1 for this Bhupesh.

Additionally, I would suggest to add support for;
1. Point query
2. Returning any row version

The above two are key features of HBase and should be supported.

Regards,
Sandeep
