-----------------------------------------
Hi Sean
I do not think it is the same error. In the related to bug, I could not create
a udf using sqlcontext. The work around solution was to change the permission
on hdfs:///tmp The error msg actually mentioned problem with /tmp. (I thought
the msg referred to the file:///tmp ) not sure how permission got messed up?
maybe some one deleted it by accident and spark does not recreated it if its
missing?
so I am able to create udf using sqlcontext. hiveContext does not work. Given I
fixed the hdfs:/// permission problem I think its probably something else.
Hopefully the attached notebook makes it easy to reproduce
thanks
Andy
