Project: Spark
Issue Type: Sub-task
Components: SQL

Add at least one test for the error class *CANNOT_CAST_DATATYPE* to
QueryExecutionErrorsSuite. The test should cover the exception throw in
QueryExecutionErrors:
{code:scala}
def cannotCastFromNullTypeError(to: DataType): Throwable = {
new SparkException(errorClass = "CANNOT_CAST_DATATYPE",
messageParameters = Array(NullType.typeName, to.typeName), null)
}
{code}
For example, here is a test for the error class *UNSUPPORTED_FEATURE*:
