Change subject: IMPALA-5293: Turn insert clustering on by default ...................................................................... IMPALA-5293: Turn insert clustering on by default This change enables clustering by default. IMPALA-2521 introduces the 'clustered' hint which inserts a local sort by the partitioning columns to a query plan. Specifying 'clustered' will now issue a warning. The hint is only effective for HDFS and Kudu tables. Like before, the 'noclustered' hint prevents clustering. If a table has ordering columns defined, the 'noclustered' hint is ignored and we issue a warning. This change also changes the behavior for Kudu tables. Specifying 'clustered' will no longer force clustering. Instead, clustering is always enabled except in these cases: * the 'noclustered' hint is present * the plan only involves a single execution node * the target table is unpartitioned. This change removes some tests that were added specifically to test that clustering can be enabled using the 'clustered' hint. It changes some tests to use the 'noclustered' hint to make sure that clustering can be disabled. It also adds tests to make sure that we cover the 'noclustered' case properly. Cherry-picks: not for 2.x.
