Subject Haddop 0.17.2 configuration problems!
Date Thu, 21 Aug 2008 18:04:50 GMT
I'm trying to install Hadoop 0.17.2 version on a linux box (xen os)

So, bin/start-all.sh works fine, but
hadoop-hadoop-jobtracker-softtek-helio-dev.log shows me error showed below.
Do you now how to fix it?

Thanks in advance
