The fix for HIVE-3140 started indenting multi-line comments, which breaks Impala testing when run against Hive 2.1.1. To test this using the pure test runner proved difficult since it would require extensive changes to support both row_regexes (since the columns changed order) and subset support (since the number of rows changed). Instead, we manually verify the hints are present in the output in the python test. The fact that the hints have been reformatted leaves us in an uncertain state as to whether they actually get applied, so a new test case has been added to run EXPLAIN SELECT on the view and verify the joins happen exactly as we expect. Testing: Ran the views-ddl test against Impala mini-cluster setups using both Hive 2.1.1 and Hive 1.1.0 Change-Id: I49e53b1230520ca6e850af28078526e6627d69de Reviewed-on: http://gerrit.cloudera.org:8080/8719 Reviewed-by: Alex Behm <alex.behm@cloudera.com> Tested-by: Impala Public Jenkins
