Description

Reported by Alex:

https://github.com/apache/incubator-hudi/blob/master/hudi-client/src/main/java/org/apache/hudi/table/HoodieCopyOnWriteTable.java#L200

this sets an Avro Schema on the config
 
but I see that AvroReadSupport.init is getting a different config instance, with avro schema set to null and falls back to what is in parquet. Which breaks during the old/new data merge. I’m pretty sure it worked before as we had successful schema evolutions. Any idea why it might be happening?
