Does avro support Generic Record with map values that are records?

[Sameer Deokule]

Hello,

  I am observing class cast exceptions while building a generic record that
has
  Map values of record types. The map value schema itself is nested and the
record
  type for the map value can be either a record or a string, with the
latter record
  being again a record that has a schema.

  Is this something that has been tested/used via a generic record?

   Attaching schema with which I observe exceptions while encoding the
built record.

Thanks
Sameer
