Subject [jira] [Commented] (HIVE-17884) Implement create, alter and drop workload management triggers.
Date Wed, 25 Oct 2017 00:57:01 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16217941#comment-16217941

Prasanth Jayachandran commented on HIVE-17884:
----------------------------------------------

Found some issue when trying out this patch and other RP patch

Hive.geAllResourcePlans() -> Hive.getAllResourcePlans()

Will this patch also support show triggers or will it be in a separate patch?

IMetaStoreClient.java is missing getTriggersForResourcePlan API (assuming client will be allowed
to retrieve Triggers independently without going via getResourcePlan).

Hive.java is missing similar getTriggersForResourcePlan.

Looks good otherwise.

> Implement triggers for workload management:
> The commands to be implemented:
> CREATE TRIGGER `resourceplan_name`.`trigger_name` WHEN condition DO action;
> condition is a boolean expression: variable operator value types with 'AND' and 'OR'
support.
> action is currently: KILL or MOVE TO pool;
> ALTER TRIGGER `plan_name`.`trigger_name` WHEN condition DO action;
> DROP TRIGGER `plan_name`.`trigger_name`;
> Also add WM_TRIGGERS to information schema.
