Nandor Kollar commented on PIG-5318: ------------------------------------ Thanks [~rohini] and [~kellyzly] for your review! Hm, I think I understood the point of TestStoreInstances, and indeed, my change on that test looks pointless. I'm afraid this might be a bug and not a test issue. I'll continue the investigation why it is failing, and what how to fix it, so far it looks like commitTask is not called on the correct OutputCommitterTestInstances instance, the array is empty. > Unit test failures on Pig on Spark with Spark 2.2 > ------------------------------------------------- > > Key: PIG-5318 > URL: https://issues.apache.org/jira/browse/PIG-5318 > Project: Pig > Issue Type: Bug > Components: spark > Reporter: Nandor Kollar > Assignee: Nandor Kollar > Attachments: PIG-5318_1.patch > > > There are several failing cases when executing the unit tests with Spark 2.2: > {code} > org.apache.pig.test.TestAssert#testNegativeWithoutFetch > org.apache.pig.test.TestAssert#testNegative > org.apache.pig.test.TestEvalPipeline2#testNonStandardDataWithoutFetch > org.apache.pig.test.TestScalarAliases#testScalarErrMultipleRowsInInput > org.apache.pig.test.TestStore#testCleanupOnFailureMultiStore > org.apache.pig.test.TestStoreInstances#testBackendStoreCommunication > org.apache.pig.test.TestStoreLocal#testCleanupOnFailureMultiStore > {code} > All of these are related to fixes/changes in Spark. > TestAssert, TestScalarAliases and TestEvalPipeline2 failures could be fixed > by asserting on the message of the exception's root cause, looks like on > Spark 2.2 the exception is wrapped into an additional layer. > TestStore and TestStoreLocal failure are also a test related problems: looks > like SPARK-7953 is fixed in Spark 2.2 > The root cause of TestStoreInstances is yet to be found out. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
