> Consider a path /a/b/c 
> Assume, I write the avro to folder using apache spark.
> After it is written, Assume I try to append dataset to this to folder. 
> I want to see the specification of what happens in case of append.
> After doing PoC, I found out that when dataet which is appended is having 
> same schema as of existing data, data gets just appended. But I want to see 
> clear docs of what happens exactly in case of append.
> I am attaching my testing java code.
