Thanks for sorting this out and contributing a PR.
Do you know if this change specific to CDH 5.7.0 is intentional - do you
know if there's a JIRA or if this is in a change list or Cloudera supports talk
about this? This seems odd that Apache Spark release 1.6.0 works but Spark 1.6
in CDH 5.7.0 does not (though it has happened before)
