Please help: Processes with HiveContext slower in cluster

Hi,

I have a HiveContext job which takes less than 1 minute to complete in local mode with 16 cores.
However, when I launch it over stand-alone cluster, it takes for ever, probably can't even finish. Even when I have the same only node running up in which I execute it locally.

How could I diagnose this issue? where can I start?

Thanks!
Saif
