Description

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.
