Wenzhe Zhou has uploaded a new patch set (#2). ( http://gerrit.cloudera.org:8080/17502 )
Change subject: IMPALA-10197 (Part 2): Add KUDU_REPLICA_SELECTION query option ...................................................................... IMPALA-10197 (Part 2): Add KUDU_REPLICA_SELECTION query option The previous patch added a new test case in PlannerTest for Kudu, which check for specific number of scan nodes and instances for distributed plan with query option KUDU_REPLICA_SELECTION set as LEADER_ONLY. However, the leadership isn't deterministic since each Kudu partition has its own Raft group and the leaders of these groups are not exactly balanced across a cluster. There's no guarantee that we'll get a certain number of leader nodes for a query which access multiple KUDU partitions. This make the unit-test flaky. This patch removed the queries which access multiple KUDU partitions for the test case with KUDU_REPLICA_SELECTION set as LEADER_ONLY. Also removed the corresponding queries for the test case with KUDU_REPLICA_SELECTION set as CLOSEST_REPLICA. Testing: - Reran the Planner test and verified the issue did not happen.
