[ https://issues.apache.org/jira/browse/FALCON-1530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14953143#comment-14953143 ]
Ajay Yadava commented on FALCON-1530:
-------------------------------------
[~pragya.mittal] Just to clarify the service response is fine but there are errors in logs, right?

> Key: FALCON-1530
> URL: https://issues.apache.org/jira/browse/FALCON-1530
> Project: Falcon
> Issue Type: Bug
> Environment: QA
> Reporter: Pragya Mittal
>
> In distributed environment, SLA monitoring API gives null response even though there are instances having SLA miss with EntityNotRegisteredException.
> This happens under following scenario:
> On deleting entity, it gets removed from store but the checkpoint is still present in list of sla pending instances. Hence, hitting sla monitoring api after deleting entity will keep on looking for deleted entity which will eventually lead to failure.
