liyunzhang_intel updated PIG-4374:
----------------------------------
Attachment: PIG-4374_6.patch
review board:https://reviews.apache.org/r/30299/
after testing in my jenkin’s, comparing the test result with
https://builds.apache.org/job/Pig-spark/97/testReport/ (125failures). following
unit tests fail:
// merge join
org.apache.pig.test.TestMergeJoin.testExpressionFail
//skewedjoin
org.apache.pig.test.TestJoinSmoke.testSkewedJoinWithGroup
org.apache.pig.test.TestSkewedJoin.testSkewedJoinWithGroup
org.apache.pig.test.TestSkewedJoin.testSkewedJoinManyReducers
org.apache.pig.test.TestSkewedJoin.testSkewedJoinOneValue
org.apache.pig.test.TestSkewedJoin.testSkewedJoinWithNoProperties
org.apache.pig.test.TestSkewedJoin.testSkewedJoinEmptyInput
// a complicated case using both 'group' and 'split'
org.apache.pig.test.TestScalarAliases.testScalarAliasesSplitClause
Because SparkCompiler#visitSkewedJoin and SparkCompiler#visitMergeJoin are not
implemented. All unit tests about these two fail.
org.apache.pig.test.TestScalarAliases.testScalarAliasesSplitClause is about a
complicated case using both 'group' and 'split'. I will investigate how to fix
TestScalarAliases.testScalarAliasesSplitClause later.

> in current code, there are following class in mapreduce and tez package.
> mapreduce:
> MRCompiler
> MROperPlan MROpPlanVisitor
> MapReduceOper
> tez:
> TezCompiler
> TezOperPlan TezOpPlanVisitor
> TezOperator
> Following class needs to be added in spark package:
> SparkCompiler
> SparkOperPlan SparkOpPlanVisitor
> SparkOperator
> Current code need to be refactored because of above adding classes. Some unit
> tests like TestStoreInstances fail because of it.
> following are the error of unit test TestStoreInstances:
