Subject [jira] [Commented] (MAPREDUCE-4422) YARN_APPLICATION_CLASSPATH needs a documented default value in YarnConfiguration
Date Fri, 13 Jul 2012 23:26:36 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13414145#comment-13414145
] 

Alejandro Abdelnur commented on MAPREDUCE-4422:
-----------------------------------------------

Ahmed, one NIT I see: The default value should be a String[], doing the "....".split() in
teh constant definition. Then when using it as default value there is not split() call over
and over.

> MAPREDUCE-3505 allowed YARN_APPLICATION_CLASSPATH to be configurable.
> However, we didn't add a default value to YarnConfiguration, as-is the norm.
> Ran into it while investigating MAPREDUCE-4421.
