Description

Hello,

I think we have the same problem as AVRO-2212.

I have classCassException with a bigDecimal.

 

Context : 

I am doing an ETL with postgres >> KafkaConnect >> KafkaStream

I get schemas with mvn schema-registry:download

 I generate pojo with : mvn clean avro:schema

Then I launch my app to stream a table source to a table target

see schema here : table.avsc

 

I have fixed passing on the 1.10.1 version and it works. But When i take 1.10.2 I have the bug :
