Identify each column name and its data in region server coprocessor

Hi,

I wanted to intercept the phoenix queries in hbase region server coprocessor and process certain columns individually.
               While receiving data in coprocessor postScannerNext method, each row is consolidated into single cell.
And cannot be distinguished separately as particular column. Along with that column family and column qualifier is fake. Is there any way to identify each column name and its data separately?

Executing command select NAME, PHONE,AMOUNT,CREDIT_CARD,DATE from "test_no"
Coprocessor is getting all value in single cell i.e.
               value =>_xyz���_�������_��������_�� qualifier => family =>_v row =>���_ timestamp =>1451242428238

note: we have added the our coprocessor in hbase-site.xml

thanks,
Vineet
