Suhas Satish commented on HIVE-8616:
------------------------------------
Even with this merged into spark branch, the following 2 rules in
SparkCompiler.java need to be enabled for dependent map-join follow-up jiras -
SparkCompiler.java -
opRules.put(new RuleRegExp(new String("Convert Join to Map-join"),
JoinOperator.getOperatorName() + "%"), new SparkMapJoinOptimizer());
opRules.put(new RuleRegExp("No more walking on ReduceSink-MapJoin",
MapJoinOperator.getOperatorName() + "%"), new SparkReduceSinkMapJoinProc());
> convert joinOp to MapJoinOp and generate MapWorks only [Spark Branch]
