      Description

      This JIRA is to track issues related to common map-join support in Spark, including logical and physical optimizations. HIVE-8616 provided initialial processing, mainly represented by SparkMapJoinOptimizer. We need to continue the work to make map join work from end to end, including enhancement needed for SparkMapJoinOptimizer and subsequent physical optimization SparkMapJoinResolver.
