    @dustinvanstee looked good.  The 'gotchya' was Spark 2.2.0 officially dropped java 7 support, so those binaries are compiled with java8[1].  I found that out by googling the error in travis[2]
    
    Because I'm curious- try changing [3] to `openjdk8` and see what happens. Will need further discusion about releasing Java8 for spark2 compatability on dev, but first lets see if it works.
