Change subject: IMPALA-13631: (Addendum) Retry aborted concurrent DDLs ...................................................................... IMPALA-13631: (Addendum) Retry aborted concurrent DDLs TestConcurrentDdls has several exceptions it considers acceptable for testing; it would accept the query failure and continue with other cases. That was fine for existing queries, but if an ALTER RENAME fails subsequent queries will also fail because the table does not have the expected name. With IMPALA-13631, there are two exception cases we need to handle: 1. "Table/view rename succeeded in the Hive Metastore, but failed in Impala's Catalog Server" happens when the HMS alter_table RPC succeeds but local catalog has changed. INVALIDATE METADATA on the target table is sufficient to bring things in sync. 2. "CatalogException: Table ... was modified while operation was in progress, aborting execution" can safely be retried. The last exception case is removed, as it was not correctly formatted and would not have matched the exception if it was thrown. Tested by running test_concurrent_ddls.py 15 times. The 1st exception previously would show up within 3-4 runs, while the 2nd exception happens pretty much every run.
