    Description

      When running in cluster mode (yarn), spark runner fails on deserialization of MicrobatchSource

      After changes made in BEAM-921 spark runner fails in cluster mode with the following:

      This seems to be caused by ClassLoader issues in the executor.

      Reverting BEAM-921 dose not remedy the situation because the previous version, in turn fails to deserialize as well with:

      java.lang.UnsupportedOperationException
