Subject Re: NPE stacktrace

Your functions can alway print to sysout or syserr (for example on
exceptions). It will be redirected to the *.out files in the Flink log
directory.

The TaskManagers themselves should log the exceptions that cause tasks to
fail.

The JobManager should also display exceptions that cause failure in the web
frontend.

This is not specific to NullPointerExceptions, however.

Does this help?
