Date Thu, 22 Sep 2016 06:47:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5611?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15512376#comment-15512376

Sunil G commented on YARN-5611:
-------------------------------

Thanks [~rohithsharma], few high level comments.
  1.
{code}
	    long newLifetime = newAppTimeouts.getLifetime();
            if (newLifetime < 0) {
{code}
{{newLifetime}} can be 0. Is there any special meaning for timeout value of 0. i could not
find any special handling for that.
If there are no special handling, we could validate that out to avoid some extra code cycles.


2.  {{rmContext.getRMAppLifetimeMonitor().updateApplicationLifetime()}} needs to check whether
app was already registered earlier. 
3. I think we can publish this information to timeline also through appUpdated event .
