Kevin Risden commented on CALCITE-2238:
---------------------------------------

Think I may have found an easy fix for this. Looks like this is a problem with 
Apache Hadoop <2.7.4. HADOOP-14586 introduces a fix for JDK 9+ to handle 
version strings like -ea. Will put up a PR if the locally running tests pass.

> JDK 10 - Pig module test failures
