   > @umehrot2 @zhedoubushishi generally speaking, this schema namespace mismatch.. is
this a backwards incompatible change.. i.e if we people have written data using 0.5.1, could
they use master/0.6.0 to read and write without pain?
   
   @vinothchandar with 0.5.1 currently you cannot even write some of these complex data types
like Array or structs etc. So this is actually a fix, and is not backwards incompatible with
0.5.1 since it uses `spark-avro`. However, it will be backwards incompatible with `databricks-avro`.
So anyone who has written data using `databricks-avro` will face issues reading.
