Subject [jira] Commented: (HADOOP-191) add hadoopStreaming to src/contrib
Date Tue, 02 May 2006 22:45:47 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-191?page=comments#action_12377484 ] 

Doug Cutting commented on HADOOP-191:
-------------------------------------

Most of the changes to the top-level build.xml don't seem to be required, and a number are
spurious whitespace and comment changes.  It seems to build fine with only the new targets
added.

Also, is the new bin/ script required?  Won't 'bin/hadoop jar build/hadoop-streaming.jar ...'
suffice?  (You'll need to set the "Main-Class" attribute in the jar's manifest.)
