Subject [jira] [Commented] (YARN-1745) Add yarn.dispatcher.exit-on-error to yarn-default.xml
Date Fri, 21 Feb 2014 19:35:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-1745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13908719#comment-13908719

Hitesh Shah commented on YARN-1745:

Also, this would be an incompatible change for all other systems using Yarn's AsyncDispatcher
code. If this change is made, it should be called out very clearly and only go into 3.x (
not in any release of 2.x ).

> This property is handled in code really weirdly.  There's a default value of false supplied
in Dispatcher.java, but everywhere that uses it in the code explicitly sets it to true.
> We should change the default in Dispatcher.java to true and add it with this same value
to yarn-default.xml.
> We'll also need a MapReduce JIRA for making the relevant changes in the JobHistoryServer.
