Wangda Tan commented on YARN-5556:
----------------------------------
Thanks [~Naganarasimha],
Generally looks good, few minor suggestions:
1) CSQueueManager:
- Better to update warn to info:
{code}
LOG.warn("Deleting Queue " + queueName + ", as it is not"
+ " present in the modified capacity configuration xml");
{code}
Since delete queue is a normal behavior
- "seems to be deleted" -> "is deleted from the new configuration"
- In {{updateQueues}}, oldQueues -> existingQueues
2) ParentQueue:
- In the "// remove the deleted queue in the refreshed xml", oldQueueName ->
queueName
And for your comment above:
bq. Better to append the exception message ...
Agree
bq. documentation needs to be updated, can either raise a new jira or add as
part of this jira for the steps to be delete the Queue in CS
It's better to have a separate JIRA to add document.
