> For transactional tables, that property might be overriden to 1, which can lead to merging final aggregation into a single stage (hence leading to performance degradation). For instance, when autogather column stats is enabled, this can happen for the following query:
> {code}
> set hive.support.concurrency=true;
> set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
> EXPLAIN
> CREATE TABLE x STORED AS ORC TBLPROPERTIES('transactional'='true') AS
> SELECT * FROM SRC x CLUSTER BY x.key;
> {code}
