Major Description
WindowSpecDefinition checks start < less, but CalendarIntervalType is not comparable, so it would throw the following exception at runtime:
scala.MatchError: CalendarIntervalType (of class org.apache.spark.sql.types.CalendarIntervalType$) at org.apache.spark.sql.catalyst.util.TypeUtils$.getInterpretedOrdering(TypeUtils.scala:58) at org.apache.spark.sql.catalyst.expressions.BinaryComparison.ordering$lzycompute(predicates.scala:592) at org.apache.spark.sql.catalyst.expressions.BinaryComparison.ordering(predicates.scala:592) at org.apache.spark.sql.catalyst.expressions.GreaterThan.nullSafeEval(predicates.scala:797) at org.apache.spark.sql.catalyst.expressions.BinaryExpression.eval(Expression.scala:496) at org.apache.spark.sql.catalyst.expressions.SpecifiedWindowFrame.isGreaterThan(windowExpressions.scala:245) at org.apache.spark.sql.catalyst.expressions.SpecifiedWindowFrame.checkInputDataTypes(windowExpressions.scala:216) at org.apache.spark.sql.catalyst.expressions.Expression.resolved$lzycompute(Expression.scala:171) at org.apache.spark.sql.catalyst.expressions.Expression.resolved(Expression.scala:171) at org.apache.spark.sql.catalyst.expressions.Expression$$anonfun$childrenResolved$1.apply(Expression.scala:183) at org.apache.spark.sql.catalyst.expressions.Expression$$anonfun$childrenResolved$1.apply(Expression.scala:183) at scala.collection.IndexedSeqOptimized$class.prefixLengthImpl(IndexedSeqOptimized.scala:38) at scala.collection.IndexedSeqOptimized$class.forall(IndexedSeqOptimized.scala:43) at scala.collection.mutable.ArrayBuffer.forall(ArrayBuffer.scala:48) at org.apache.spark.sql.catalyst.expressions.Expression.childrenResolved(Expression.scala:183) at org.apache.spark.sql.catalyst.expressions.WindowSpecDefinition.resolved$lzycompute(windowExpressions.scala:48) at org.apache.spark.sql.catalyst.expressions.WindowSpecDefinition.resolved(windowExpressions.scala:48) at org.apache.spark.sql.catalyst.expressions.Expression$$anonfun$childrenResolved$1.apply(Expression.scala:183) at org.apache.spark.sql.catalyst.expressions.Expression$$anonfun$childrenResolved$1.apply(Expression.scala:183) at scala.collection.LinearSeqOptimized$class.forall(LinearSeqOptimized.scala:83)
