Subject [jira] Commented: (MAPREDUCE-258) Update MapOutputServlet to use NIO channels
Date Wed, 26 Aug 2009 08:49:59 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747841#action_12747841
] 

Greg Wilkins commented on MAPREDUCE-258:
----------------------------------------

The Buffer mechanism of jetty would need major surgery to convert to longs from ints. So this
is not likely to happen.
So we would need to come up with some other to send such large content.

Please comment on  http://jira.codehaus.org/browse/JETTY-748 when you are interested in looking
at this again and we 
can discuss the possibilities.
