[jira] Commented: (HADOOP-4027) When streaming utility is run without specifying mapper/reducer/input/output options, it returns 0.

    [ https://issues.apache.org/jira/browse/HADOOP-4027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631607#action_12631607 ] 

Robert Chansler commented on HADOOP-4027:
-----------------------------------------

I surveyed some of the usual suspects and neither they nor I could conclude that the example is or should be an error. It is OK to successfully do nothing. 

I propose to resolve this a not a bug.
