Subject [jira] [Commented] (YARN-1700) AHS records non-launched containers
Date Wed, 26 Feb 2014 05:00:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-1700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13912515#comment-13912515

Gera Shegalov commented on YARN-1700:
-------------------------------------

Log URL is physically nullable, but in the current source code as is it never changes after
the launch and is not null. If the intention is to record/display even containers that have
not launched, I am fine treating it as a dup of YARN-1685

> When testing AHS with a MR sleep job, AHS sometimes threw NPE out  of AppAttemptBlock.render
because logUrl in container report was null. I realized that this is because AHS may record
containers that never launch.
