Subject [jira] Commented: (HADOOP-1650) Upgrade Jetty to 6.x
Date Mon, 03 Nov 2008 22:16:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12644828#action_12644828
] 

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

I'm currently working on a Jetty extension that will better suit the Hadoop use case, namely
serving ranges of very large files.    The extension will wrap a RandomAccessFile instance
as a Jetty buffer and thus will be able to be passed to in Http Generator within Jetty and

asynchronously flushed using FileChannel.transferTo(Channel)

This is mostly written now and we will be benchmarking this shortly.

Unfortunately, this will not make it into the Jetty 6.1.12 final release (out later today),
but that does have some optimizations over 6.1.12.rc4

> 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.
