Yes the submitter is about to open another PR, as I understand it.

Hi, is any body working on this (and SPARK-7617, SPARK-7618)? I have been using 
Spark for some time, and would like get started contributing. This looks like a 
trivial issue (good fo a newbie).

Shall I provide a pull request for this? Would it make sense a pull request for 
the three related issues?
