Subject [jira] [Commented] (MAPREDUCE-4148) MapReduce should not have a compile-time dependency on HDFS
Date Fri, 04 May 2012 15:40:48 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13268463#comment-13268463
] 

Robert Joseph Evans commented on MAPREDUCE-4148:
------------------------------------------------

I like the patch a lot.  It cleans things up which is really good.  I think Daryn has a few
minor comments but other then that I give it a +1.  I would also like to try and pull this
into branch-0.23.  The patch seems to apply OK for branch-0.23, but if you do need any help
with it I am happy to do it for you.

> MapReduce depends on HDFS's DelegationTokenIdentifier (for printing token debug information).
We should remove this dependency and MapReduce's compile-time dependency on HDFS.
