Subject Jetty can't start the SelectChannelConnector
Date Tue, 06 Apr 2010 19:44:25 GMT
Hi all,

I configured the Hadoop in a cluster and the NameNode and JobTracker are
running ok, but the DataNode and TaskTracker Doesn't start, they stop and
keep waiting
when they are going to start the Jetty

I observed that Jetty can't start the _SelectChannelConnector_

Is there any Jetty configuration that should be changed ?

There is no log message in the NN and JT when I try to start the DN and TT.

The kernel I'm using is:
Linux bl05 2.6.32.10 #2 SMP Tue Apr 6 12:33:42 BRT 2010 x86_64 GNU/Linux

This is the message when I start the DN. It happens with TT too.
