Jesus Camacho Rodriguez commented on HIVE-13518:
------------------------------------------------
LGTM, +1.
Nitpick: {{getMapJoinConversionPos}} could be renamed, as it does not apply
only to MapJoin anymore (getBigTablePos?)
> Hive on Tez: Shuffle joins do not choose the right 'big' table.

> Currently the big table is always assumed to be at position 0 but this isn't
> efficient for some queries as the big table at position 1 could have a lot
> more keys/skew. We already have a mechanism of choosing the big table that
> can be leveraged to make the right choice.
