[jira] [Commented] (HIVE-8536) Enable runtime skew join optimization for spark [Spark Branch]

    [ https://issues.apache.org/jira/browse/HIVE-8536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14209083#comment-14209083 ] 

Rui Li commented on HIVE-8536:
------------------------------

Runtime skew join should be processed by two resolvers: {{SkewJoinResolver}} and {{MapJoinResolver}}. The following patch makes {{SkewJoinResolver}} to work with spark. I'll need {{SparkMapJoinResolver}} in place to continue the work.
