Hi Devendra,

Tried this option but did not work. Do you suggest any other way?

Hi,

You can set the Locality of the parser and the writer to Container local.

This will ensure that Generic Record from the parser does not get serialized 
between containers.

Thanks,
Dev

Hi,

Can you please help resolve the below issue?

In our project we are using ‘org.apache.avro.generic.GenericRecord’ as Tuple 
writing to a parquet file and we are using avro schema for each record. We are 
getting the below exception, I suppose GenericRecord does not have no-arg 
constructor, and looking for some ideas to solve this problem.
