Review request for drill, Jacques Nadeau, Jinfeng Ni, Steven Phillips, and
Venki Korukanti.
Changes
-------
Addressing review ocmments
Bugs: DRILL-2209
https://issues.apache.org/jira/browse/DRILL-2209
Repository: drill-git
Description
-------
Insert Project operator to add new column "EXPRHASH" with hash expression for
fields that are used for HashToRandomExchange
Remove Project operator after HashRandomExchange (or Demux) since it will
create problems to fields ordering in HashJoin.
Tight this to MuxExchange - so if MuxExchange is enabled, Project is inserted.
