Hi Lokesh, There is no way to do that. SqlContext.newSession documentation says:
Returns a SQLContext as new session, with separated SQL configurations, temporary tables, registered functions, but sharing the same SparkContext, CacheManager, SQLListener and SQLTab. You have two options: either use the same SQLContext instead of creating new SQLContexts, or have a function for creating SQLContexts, and this function can also register the UDFs in every created SQLContext.
