Greg Wilkins commented on HADOOP-1650:
--------------------------------------

just a progress report on the work we are doing in jetty to support the hadoop use-case of sending large ranges from huge files.   We've implemented a RandomAccessFileBuffer that allows NIO to efficiently send parts of files.
We've updated our HttpGenerator to be able to use this.

This is checked into jetty trunk and we are testing now.

In a week or two, we hope to have some benchmarks and some instructions as to how to use this with hadoop.

You can watch progress at http://jira.codehaus.org/browse/JETTY-748

cheers

> This is the third attempt at moving to jetty6. Apparently, the jetty-6.1.4 has fixed some of the issues we discovered in jetty during HADOOP-736 and HADOOP-1273. I'd like to keep this issue open for sometime so that we have enough time to test out things.
