Subject [jira] [Commented] (APEXCORE-503) support KillException
Date Wed, 18 Jan 2017 07:39:26 GMT

    [ https://issues.apache.org/jira/browse/APEXCORE-503?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15827550#comment-15827550

Amol Kekre commented on APEXCORE-503:

This is a good idea. We could have a way for operator to inform the Stram to initiate graceful
shutdown. Then Stram can orchestrate that. A possile ways could be to

1. Initiate shutdown via control tuple through input operators. But this causes slow operators
which are behind to lag till they catch up and then shutdown.
2. Stram issues a shutdown to StramChild (this exists today, aka same result as if the shutdown
came from a webservice).

> Current way for Operators to stop the whole app is to use "ShutdownException". But it
is considered as a graceful stop. To stop the whole App when an error condition happens, new
exception should be supported, called "KillException" or "KillAppException.
