Subject [jira] [Commented] (YARN-5611) Provide an API to update lifetime of an application.
Date Mon, 31 Oct 2016 21:35:59 GMT

    [ https://issues.apache.org/jira/browse/YARN-5611?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15623498#comment-15623498
] 

Jian He commented on YARN-5611:
-------------------------------

- What is the reason to involve RMAppImpl state-machine to update the application timeout
? I think it's simpler to update directly, not go through the RMAppImpl state machine..
- This code
{code}
    Map<ApplicationTimeoutType, Long> newApplicationExpireTime =
        new HashMap<ApplicationTimeoutType, Long>();
    newApplicationExpireTime.putAll(newParsedTimeouts);
{code}
can be changed to 
{code}
    Map<ApplicationTimeoutType, Long> newApplicationExpireTime =
        new HashMap<ApplicationTimeoutType, Long>(newParsedTimeouts);
{code}
- I wonder whether we need a separate wrapper class "AppUpdateAttributes" for the timeout,
is it fine to just put application timeout in the ApplicationStateData class?
