Impala admission control for DDL statements

[ Edited ]

With Impala admission control we can only control query and DML statements using Max Running Queries param.


In our environment users are triggering multiple DDL statements, in some cases same DDL statement conteniously (e.g 10 "refresh abc" at same point of time).

Is there any way we can control DDL flow?

can catalog detect and reject same statement if one is in progress?

Re: Impala admission control for DDL statements

Unfortunately, Impala does not currently provide any way to apply admission control to DDL statements
