Sergey Soldatov commented on PHOENIX-1973:
------------------------------------------
[~enis] it was rolled back because of PHOENIX-2716. I removed table index from
TableRowKeyPair since PhoenixWriter expects the real table name to decide in
which split the KV is supposed to be written. Because this information is
keeping in the job configuration passing indexes back and forth can be tricky
and can cause some other side effects.

> 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.
