Sunitha Kambhampati commented on SPARK-23798:
---------------------------------------------
ArrayType.defaultConcreteType is ArrayType(NullType, containsNull = true)
But this pr [https://github.com/apache/spark/pull/18516] made changes to have
CreateArray return the default ArrayType of elementType to be StringType.

> The CreateArray and ConcatArray should return the default array type when no
