Jimmy Xiang updated HIVE-9042:
------------------------------
Attachment: HIVE-9042.1-spark.patch
Attached patch v1 which is on RB: https://reviews.apache.org/r/28864/
In one work, there could be multiple mapjoin operators. But only one could be
bucket mapjoin. The patch makes sure, we set the bucket mapjoin context for the
right work only.
