LGTM. One suggestion below for testing.

http://gerrit.cloudera.org:8080/#/c/16007/7/testdata/workloads/functional-planner/queries/PlannerTest/tpcds-all.test
File testdata/workloads/functional-planner/queries/PlannerTest/tpcds-all.test:

http://gerrit.cloudera.org:8080/#/c/16007/7/testdata/workloads/functional-planner/queries/PlannerTest/tpcds-all.test@9036
PS7, Line 9036: |--90:EXCHANGE [UNPARTITIONED]
This query seems to be a special case where both left and right inputs of the 
NLJ happen to be 1 row and hence none of the exchanges are BROADCAST which is 
the more common case.  IT would be nice to have one explain with the common 
case (need not be the complex TPC-DS query..it could be one of the simplified 
queries).
