holdenk updated SPARK-15369:
----------------------------
Description: Transferring data from the JVM to the Python executor can be a
substantial bottleneck. While Jython is not suitable for all UDFs or map
functions, it may be suitable for some simple ones. We should investigate the
option of using Jython to accelerate these small functions. (was: Transfering
