The file "records.avro"  is generated using avro-1.8.2 .  It contains two  records  and using "avro-tools-1.8.2.jar"  one can read it.  If   we use   "avro-tools-1.9.2.jar", then "records.avro"  is not readable  (as shown above).  The file "records.avro"  is also  attached for your convenience. 

 

Let me know if you need any more information.

 

Thanks,

Manoj
