Subject Re: Jetty can't start the SelectChannelConnector
Date Tue, 06 Apr 2010 22:37:44 GMT
Hi Todd,

I'm getting this behavior in another cluster too, there the same thing
happens.
and as I don't have a jstack installed in the first cluster and
I'm not the admin, I'm sending the results of the second cluster.

These are the results:

[erlf07@cohiba ~ ]$ jstack  -l 22510
22510: well-known file is not secure
[erlf07@cohiba ~ ]$ jstack -l 3836
3836: well-known file is not secure

The jstack -F result is in thread_dump files and the jstack -m result is in
java_native_frames.

The files ending with nn are the namenode results and the files ending with
dn are the datanode results.

Thanks,

Edson Ramiro
