Miguel Duarte updated SPARK-33330:
----------------------------------
Description:
Given that:
# JavaTypeInference maps [Enums to
StringType|https://github.com/apache/spark/blob/55105a0784459331d5506eee9f37c2e655a2a6a0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/JavaTypeInference.scala#L135]
# The converter for [StringType is
StringConverter|https://github.com/apache/spark/blob/55105a0784459331d5506eee9f37c2e655a2a6a0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/CatalystTypeConverters.scala#L64]
# StringConverter is unable to convert an [Enums to
UTF8String|https://github.com/apache/spark/blob/55105a0784459331d5506eee9f37c2e655a2a6a0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/CatalystTypeConverters.scala#L294],
failing with an InvalidArgumentException
It can be argued that CatalystTypeConverters should align with the
exprectations set by JavaTypeInference and convert enums to their string
representation.
Edit:
Added PRs for 3.0.X and 2.4.X branches
was:
