Mohit,
You can use this patch to suit your need:
https://issues.apache.org/jira/browse/PIG-2579
New fields in Avro schema descriptor file need to have a non-null default
value. Hence, using the new schema file, you should be able to read older
data as well. Try it out. It is very straight forward.
Hope this helps!
Thanks! I am new to Avro what's the best place to see some examples of how
Avro deals with schema changes? I am trying to find some examples.

I am not sure how it could be done without keeping some kind of structure
along with the data. Are there any good examples and documentation that I
can look at?
