Subject [jira] [Commented] (FALCON-2148) Entries not removed from sla list when instance succeeds
Date Wed, 21 Sep 2016 13:55:20 GMT

    [ https://issues.apache.org/jira/browse/FALCON-2148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15509977#comment-15509977

Praveen Adlakha commented on FALCON-2148:

Hi [~sandeep.samudrala]

Few more things we need to consider here what if a process get killed before its SLAhigh is

If it gets deleted from the pending_instances we will never be able to report the SLA miss
to the BacklogEmitterService so we cannot delete it just like that. I believe it should only
get deleted in case of success rest of the states should account for the backlog.


One case that comes to my mind in this scenario:

Let's say we have metadata loading job or some other job in which only the last instance matters
i.e if the last instance has completed on time there is no backlog.

In these kinds of case's we will keep on reporting backlog for the failed instances which
is not true how do you suggest we should handle this?

> Entries corresponding to a process sla should be removed if the process goes from WAITING
to SUCCEEDED state. The same is not happening.
