save RDD of Avro GenericRecord as parquet throws UnsupportedOperationException

[Govindasamy, Nagarajan]

Hi,

I am trying to save RDD of Avro GenericRecord as parquet. I am using Spark 
1.6.1.

DStreamOfAvroGenericRecord.foreachRDD(rdd => 
rdd.toDF().write.parquet("s3://bucket/data.parquet"))

Getting the following exception. Is there a way to save Avro GenericRecord as 
Parquet or ORC file?

java.lang.UnsupportedOperationException: Schema for type 
org.apache.avro.generic.GenericRecord is not supported
