> Reporter: Thai Bui
> Assignee: Thai Bui
> Priority: Minor
>
> During testing of the new WM feature and the Hive metastore is created using
> Postgresql, I've discovered a bug when creating a new trigger. For example
> {noformat}
> CREATE RESOURCE PLAN plan_1 WITH QUERY_PARALLELISM=4;
> CREATE POOL plan_1.slow WITH
> ALLOC_FRACTION=0.5, QUERY_PARALLELISM=2, SCHEDULING_POLICY='fair';
> ALTER POOL plan_1.default SET
> ALLOC_FRACTION=0.5, QUERY_PARALLELISM=2, SCHEDULING_POLICY='fifo';
> CREATE TRIGGER plan_1.trigger_1 WHEN S3A_BYTES_READ > 268435456 DO MOVE TO
> slow;
> {noformat}
> Right at the CREATE TRIGGER statement, an error will occur
> {noformat}
> Error while processing statement: FAILED: Execution Error, return code 1 from
> org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:Insert of

> The fix is to change the IS_IN_UNMANAGED field in Postgres from boolean to
> integer (smallint) since that is what it's being done in derby schema.
