Hi Chris, I meant "Local Runner".
>From the sounds of your email, it seems that modifying the two fore-mentioned properties is not enough to get a cluster node to run as a local runner?

My ant script has included all the external jars in the lib/ directory - do I need to do the same for the xml files? thanks -- Jim On 11/1/07, Chris K Wensel <[EMAIL PROTECTED]> wrote: > Hey Jim > > what do you mean by local? > > This wiki page defines two 'local' modes. > http://wiki.apache.org/lucene-hadoop/QuickStart > > One with a local cluster, and one with all jobs running standalone. > > The conf dir that ships with Hadoop is setup for standalone. > > I find it useful to have a copy of 'conf' named 'conf-localhost' that > has the local cluster version of 'hadoop-site.xml'. then use > > > ./bin/hadoop --config ./conf-localhost .... > > to start her up..
