[jira] Created: (HADOOP-1273) Upgrade Jetty to 6.x

Michael Gibney (Jira)
Upgrade Jetty to 6.x
--------------------

                 Key: HADOOP-1273
                 URL: https://issues.apache.org/jira/browse/HADOOP-1273
             Project: Hadoop
          Issue Type: Improvement
          Components: util
    Affects Versions: 0.12.3
            Reporter: Owen O'Malley
         Assigned To: Tahir Hashmi


We should try again to upgrade to Jetty 6 (previous attempt was HADOOP-565 and HADOOP-736) because it should substantially help the cpu usage on the TaskTracker. See http://www.infoq.com/news/jetty-6-release for a discussion of the improvements to Jetty 6.

Tahir Hashmi updated HADOOP-1273:
---------------------------------

    Attachment: 1273.patch

Attaching the patch that's been applied to the current source and a tarball of the lib directory. JT and TaskTrackers info webservers start now but they give 404 for everything. Needs further investigation.

Tahir Hashmi commented on HADOOP-1273:
--------------------------------------

Status update: After more than a week of pecking at it, we managed to get a few sort-350 and sort-500 runs that performed as well as, but no better than, the jetty-5 codebase. Unfortunately, as of now we've hit some deep waters. The problems are mentioned at the following issue on Jetty: http://jira.codehaus.org/browse/JETTY-345

Tahir Hashmi commented on HADOOP-1273:
--------------------------------------

As per http://jira.codehaus.org/browse/JETTY-345#action_96904, the bug that causes EofExceptions to occur has been identifiend in a 6.1.4 release candidate. However, the port retrieval issue might still remain. I tried doing webServer.join() a few days back and it had disastrous consequences. Not sure why.

Since deploying Jetty 6 at this stage requires using an RC, and we're not sure if that's going to solve all of the problems, it might be reasonable to abandon the upgrade for now.

[jira] Resolved: (HADOOP-1273) Upgrade Jetty to 6.x

Tahir Hashmi resolved HADOOP-1273.
----------------------------------

    Resolution: Won't Fix

Since Jetty 6 still doesn't appear to be stable enough, we've decided to investigate Grizzly for the same. See HADOOP-1432 for details.
