{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)

This error message can be improved to say the plan is already active.
