[jira] Commented: (MAPREDUCE-1322) TestStreamingAsDifferentUser fails on trunk

["Amareshwari Sriramadasu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793515#action_12793515 ] 

Amareshwari Sriramadasu commented on MAPREDUCE-1322:
----------------------------------------------------

Looks like "mapreduce.jobtracker.staging.root.dir"  is not added in mapred-default.xml, but is added to src/test/mapred-site.xml. Streaming tests do not pick mapred-site.xml from src/test/. Is there any reason for not adding the configuration in mapred-default.xml?
