Thanks for finding and fixing this.

http://gerrit.cloudera.org:8080/#/c/7168/3/tests/metadata/test_explain.py
File tests/metadata/test_explain.py:

Line 105:     result = self.execute_query("explain select * from %s.%s where id 
"
Instead of this end-to-end test, please add a new FE unit test 
ExprSelectivityTest similar to ExprNdvTest. Relying on a full explain seems 
like overkill, and checking the scan cardinality is really an indirect test.
