@srowen - I added a Java api to specify `separateWorkingDir` and
`bufferSize`. For `printPipeContext` and `printRDDElement`, these are functions
which take another function as argument and there is no straightforward way to
specify these in Java (probably that's the reason they are left out in the
first place). Let me know what you think about the change.
