Sandeep Katta commented on SPARK-27917:
---------------------------------------

This can be tested using the below UT code

val attrRef = AttributeReference("ACCESS_CHECK", StringType)()
val aliasAttrRef = attrRef.withName("access_check")
val caseWhenObj1 = CaseWhen(Seq((attrRef, Literal("A"))))
val caseWhenObj2 = CaseWhen(Seq((aliasAttrRef, Literal("A"))))
assert(caseWhenObj1.semanticEquals(caseWhenObj2))

> Semantic equals of CaseWhen is failing with case sensitivity of column Names
