This method can be used to generate output rows that are based on any state information aggregated in process().
This method can be used to generate output rows that are based on any state information aggregated in process(). This method is invoked once for each partition, after all rows in that partition have been passed to process().
The rows returned in this method must match the StructType defined in outputSchema

StructType
A StructType that describes the data types of the fields in the rows returned by the process() and endPartition() methods.
A StructType that describes the data types of the fields in the rows returned by the process() and endPartition() methods.
For example, if a UDTF returns rows that contain a StringType and IntegerType field, the outputSchema() method should construct and return the following StructType object: {{ override def outputSchema(): StructType = StructType(StructField("word", StringType), StructField("count", IntegerType)) }}
