--------------------------------

Hello,

It has been 10 days since the ticket is raised but still no one assigned to it. 
Could you please provide an update. Also, I would like to if below issues are 
same as this one.
 * https://issues.apache.org/jira/browse/AVRO-2618
 * https://issues.apache.org/jira/browse/AVRO-2098

If yes, I have already tried using the latest Avro DLL 1.9.2 version but it 
gave the same error in Azure datalake analytics U-SQL job. 

Kindly look into it and update at the earliest.

Regards,

Abhilash V
