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 for PlannerTest, which check for specific number of scan nodes for query fragment instances 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, the leaders of these groups are not balanced across a cluster. There's no guarantee that we'll get a certain number of leader nodes for a query with multiple partitions. This make the unit-test flaky. This patch removed the queries with multiple partitions for the test case. Testing: - Reran the Planner test and verified the issue did not happen.
