------------------------------
Summary: Queue Management API - rephrase error messages
Key: YARN-8678
URL: https://issues.apache.org/jira/browse/YARN-8678
Project: Hadoop YARN
Issue Type: Bug
Reporter: Akhil PB
Assignee: Akhil PB
1. When stopping a running parent queue, error message thrown by API was not
meaningful.
For example: When tried to stop root queue, error message thrown was {{Failed
to re-init queues : The parent queue:root state is STOPPED, child queue:default
state cannot be RUNNING.}}
It is evident that root queue update failed, but the message says {{queue:root
state is STOPPED}}.
2. While tried to delete a running leaf queue, error message thrown by API was
not meaningful.
For example: Error message was {{Failed to re-init queues : root.default.prod
is deleted from the new capacity scheduler configuration, but the queue is not
yet in stopped state. Current State : RUNNING}}.
Clearly deletion of queue root.default.prod failed with error, but the message
says {{queues : root.default.prod is deleted from the new capacity scheduler
configuration}}.
