---------------------------------------

             Summary: Implement a similar feature like "hive.tez.dynamic.semijoin.reduction" in hive on spark
                 Key: HIVE-16862
                 URL: https://issues.apache.org/jira/browse/HIVE-16862
             Project: Hive
          Issue Type: Bug
            Reporter: liyunzhang_intel


Currently if we enable "hive.tez.dynamic.semijoin.reduction" (the default value is true) in hive on spark, following script fail
{code}
set hive.optimize.ppd=true;
set hive.ppd.remove.duplicatefilters=true;
set hive.spark.dynamic.partition.pruning=true;
set hive.optimize.metadataonly=false;
set hive.optimize.index.filter=true;
set hive.strict.checks.cartesian.product=false;
set hive.spark.dynamic.partition.pruning=true;

-- multiple sources, single key
select count(*) from srcpart join srcpart_date on (srcpart.ds = srcpart_date.ds) join srcpart_hour on (srcpart.hr = srcpart_hour.hr) {code}
{code}
the reason why this fail see HIVE-16780, currently we only disable "hive.tez.dynamic.semijoin.reduction" when running hive on spark to pass the test.  Later we can implement a similar feature like what hive on tez does.
