Matt McCline commented on HIVE-9824:
------------------------------------
I switched over to using https://github.com/apache/hive from using
git://git.apache.org/hive.git because of the read error: Connection reset by
peer problem.
I did notice when I generated the review board patch with this command line:
{noformat}
git diff --no-ext-diff HEAD^ > review_board_patch_07.txt
{noformat}
and this command line for the actual patch:
{noformat}
git diff --no-ext-diff --no-prefix HEAD^ > HIVE-9824.07.patch
{noformat}
The files had the same length.... when they usually have different lengths.

> Today's VectorMapJoinOperator is a pass-through that converts each row from a
> vectorized row batch in a Java Object[] row and passes it to the
> MapJoinOperator superclass.
> This enhancement creates specialized vectorized map join operator classes
> that are optimized.
