> It's similar to HBASE-8768. Only thing is we need to write custom mapper and reducer
in Phoenix. In Map phase we just need to get row key from primary key columns and write the
full text of a line as usual(to ensure sorting). In reducer we need to get actual key values
by running upsert query.
> It's basically reduces lot of map output to write to disk and data need to be transferred
through network.
