-----------------------------------
Even though it is short, if you put the patch on Review Board that'll make it
easier to review.

> JoinOperator.processOp logs lines like "table 0 has x rows for join key
> \[foo\]". It is supposed to log after x rows for x = i, 2i, 4i, .... However,
> it has never worked completely:
> * In 0.11.0 and before, it logs after i rows and not after >i rows, because
> nextSz is not properly updated.
> * In 0.12.0, HIVE-4960 partially fixed that but x fails to be reset when the
> alias (tag) changes.
