Subject [jira] [Updated] (FALCON-1530) SLAMonitoring API is not honouring delete feature
Date Mon, 12 Oct 2015 13:49:05 GMT

     [ https://issues.apache.org/jira/browse/FALCON-1530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pragya Mittal updated FALCON-1530:
----------------------------------
    Description: 
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.
