Subject [jira] [Commented] (YARN-4205) Add a service for monitoring application life time out
Date Sun, 04 Sep 2016 18:44:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-4205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15463327#comment-15463327

Rohith Sharma K S commented on YARN-4205:
-----------------------------------------

bq. I agree with this above sentiment - we don't need another configuration application.lifetimeout-monitor.interval-ms.
IIUC, the conversation between Sunil and Nijel had for starting another thread i.e RMAppLifetimeMonitorThread.
And I believe monitoring interval should be configurable at RM level. 

bq. The other important question is about when the clock start ticking for the life-time.
Clearly if we start it when the app gets submitted, we'd automatically also handle YARN-2266
The new patch attached will be registering in NEW_SAVING transition. Basically the time for
storing RMStateStore also part of application life timeout.  RMstatStore storing should also
part of app life time. Lifetime is considered from NEW_SAVING to completing states i.e after
RUNNING any states.

> This JIRA intend to provide a lifetime monitor service. 
> The service will monitor the applications where the life time is configured. If the application
is running beyond the lifetime, it will be killed. 
> The lifetime will be considered from the submit time.
> The thread monitoring interval is configurable.
