Exception while launching Falcon pig sample job
Hi All,
We get the following error when launching a simple (from the examples) Falcon pig job. I think I don't need to manually copy the oozie jars to HDFS.
Thanks
Venkat

Thanks Shwetha. I'll refer to Oozie doc. I believe this is a one time setup.
Thanks,

Hi Venkat,
Looks like oozie sharelib is not set-up correctly. JavaMain is part
of <oozie share lib>/oozie/oozie-sharelib-oozie-<version>.jar. Oozie
package is bundled with sharelib which contains this jar. Refer to oozie
doc for setting-up sharelib
