liyunzhang_intel created PIG-4622:
-------------------------------------
Summary: Skip TestCubeOperator.testIllustrate and
TestMultiQueryLocal.testMultiQueryWithIllustrate
Key: PIG-4622
URL: https://issues.apache.org/jira/browse/PIG-4622
Project: Pig
Issue Type: Sub-task
Reporter: liyunzhang_intel
Assignee: liyunzhang_intel
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".
illustrate.pig
{code}
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';
{code}
the exception is thrown out at
