Hey Jayant, I don't really think that the sole fact of using Predicate should cause the *ClassNotFoundException* that You are talking about. The exception may come from the fact that some libraries are missing from Your cluster environment. Have You tried running the job locally to verify that the exception occurs? Also, could You please paste some logs here, they may help in determining the exact reason for the problem.
