I am +1 on this also, although I think we need to look at moving to Jetty-7 or possibly dropping Jetty completely and look at Netty or even Tomcat long term. Jetty has just been way too unstable at Hadoop scale and that has not really changed with newer versions of Jetty. Sticking with an old

I agree that we should explore alternatives the forked version of Jetty. This is a longer term goal. In the interim, lets do jetty-6.1.26 + fixes. On Wed, Jul 11, 2012 at 6:03 AM, Robert Evans ev...@yahoo-inc.com wrote: I am +1 on this also, although I think we need to look at moving to

a bug in ViewFs tests

2012-07-11 Thread Andrey Klochkov
Hi, I noticed that the fix done in HADOOP-8036 (failing ViewFs tests) was reverted later when resolving HADOOP-8129, so the bug exists both in 0.23 and 2.0. I'm going to provide an alternative fix. Should I reopen HADOOP-8036 or create a new one instead? Thanks. -- Andrey Klochkov
