I was using BSF to avoid java 6 issues. However I'm having similar issues using both systems. Basically, I can't load the scripting engine from within hadoop. I have successfully compiled and run some stand-alone test examples but am having trouble getting anything to work from hadoop. One confounding factor is that my development machine is OS X 10.5 with the stock 1.5 JDK. On the surface this doesn't seem to be a problem given the success I've had at creating small stand-alone tests... I run the stand-alone stuff with exactly the same classpath and environment so it seems that something weird is going on. Additionally, as a sanity check, I've tried loading the javascript engine and that does work from within hadoop.
All the JSR jars are on the classpath and I'm kinking off the hadoop process using the -Djruby.home=... option. Did you have to do anything special here? -lincoln -- lincolnritter.com On Thu, Jul 24, 2008 at 7:00 PM, James Moore <[EMAIL PROTECTED]> wrote: > On Thu, Jul 24, 2008 at 3:51 PM, Lincoln Ritter > <[EMAIL PROTECTED]> wrote: >> Well that sounds awesome!
