[jira] [Commented] (YARN-1917) Add "waitForCompletion" interface to YarnClient

    [ https://issues.apache.org/jira/browse/YARN-1917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13963959#comment-13963959 ] 

Wangda Tan commented on YARN-1917:
----------------------------------

My basic thinking is we can leverage existing implementation in UnmanagedAMLauncher.monitorApplication, it should be enough for many use cases. The method could be, YarnClient.waitForCompletion(ApplicationId appId). 
Appreciate your comments :)

> Currently, YARN dosen't have this method. Users needs to write implementations like UnmanagedAMLauncher.monitorApplication or mapreduce.Job.monitorAndPrintJob on their own. This feature should be helpful to end users.
