-Getting CNF during map reduce execution

I am trying to use hive inside an OSGi enviornment. So far I faced several
OSGi issues in hive and some issues related to JDO implementation used
(datanucleaus) under the OSGi enviornemnt and was able to overcome them.
However when I run a query involving a map reduce operation I am getting a
ClassNotFound exception from hadoop side. (Hadoop is running in pseudo
distributed mode in the local machine).
I think this is probably due to some jar/ resource not being bundled
properly in to the deployed archive to Hadoop. Would some one be able to
explain a bit of how the job submission part from Hive to Hadoop works and
any possible reason for this behaviour? Any pointers to look in to the code
is also appreciated.
