Prasanth Jayachandran updated HIVE-18152:
-----------------------------------------
Description:
{code}
show resource plans;
+----------+----------+--------------------+
| rp_name | status | query_parallelism |
+----------+----------+--------------------+
| llap | ACTIVE | 1 |
| global | ENABLED | 1 |
+----------+----------+--------------------+
ALTER RESOURCE PLAN llap ACTIVATE;
Error: Error while processing statement: FAILED: Execution Error, return code 1
from org.apache.hadoop.hive.ql.exec.DDLTask. Cannot get a resource plan to
apply (state=08S01,code=1)
{code}
It is better not to throw an error when current state is same as the altered
state.
