Description

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. When running following script with "illustrate".
illustrate.pig

a = load 'test/org/apache/pig/test/data/passwd' using PigStorage(':') as (uname:chararray, passwd:chararray, uid:int,gid:int);
b = filter a by uid >5;
illustrate b;
store b into './testMultiQueryWithIllustrate.out';

the exception is thrown out at MRScriptState.get:java.lang.ClassCastException: org.apache.pig.tools.pigstats.spark.SparkScriptState cannot be cast to org.apache.pig.tools.pigstats.mapreduce.MRScriptState.
