Hi Sim, Seems you already set the PermGen size to 256m, right? I notice that in your the shell, you created a HiveContext (it further increased the memory consumption on PermGen). But, spark shell has already created a HiveContext for you (sqlContext. You can use asInstanceOf to access HiveContext's methods). Can you just use the sqlContext created by the shell and try again?
