Subject [jira] [Commented] (YARN-808) ApplicationReport does not clearly tell that the attempt is running or not
Date Sat, 29 Mar 2014 07:18:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13951792#comment-13951792

Xuan Gong commented on YARN-808:
--------------------------------

We have api/cli to get the attemptReport. So do not think we still need to expose AttemptReport
into ApplicationReport.
[~mayank_bansal] [~bikassaha] What do you think ?

> When an app attempt fails and is being retried, ApplicationReport immediately gives the
new attemptId and non-null values of host etc. There is no way for clients to know that the
attempt is running other than connecting to it and timing out on invalid host. Solution would
be to expose the attempt state or return a null value for host instead of "N/A"
