Subject [jira] Commented: (HADOOP-3366) Shuffle/Merge improvements
Date Tue, 13 May 2008 18:19:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596478#action_12596478

Sameer Paranjpye commented on HADOOP-3366:

What value does the RamFS add here? It would be simpler to just put keys/values in a buffer
and iterate over them in place. I don't see the value in special casing DataOutputBuffer for
this very specific use case.
