> it shows that in https://builds.apache.org/job/Pig-spark/236/#showFailuresLink following two unit tests fail:
> TestCubeOperator.testIllustrate and TestMultiQueryLocal.testMultiQueryWithIllustrate
> This because current we don't support illustrate in spark mode(see PIG-4621).
> why after PIG-4614_1.patch was merged to branch, these two unit test fail?
> in PIG-4614_1.patch, we edit [SparkExecutionEngine #instantiateScriptState|https://github.com/apache/pig/blob/a0bea12c3d5600a4c3137a8d05c054d10430b1ce/src/org/apache/pig/backend/hadoop/executionengine/spark/SparkExecutionEngine.java#L37]. When running following script with "illustrate".
