[jira] [Updated] (HIVE-9042) Support multiple mapjoin operators in one work [Spark Branch]

     [ https://issues.apache.org/jira/browse/HIVE-9042?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> As Xuefu pointed out, HIVE-8638 assumes there is just one mapjoin operator in one spark work. Sometimes, there could be more.
