BALAJI VARADARAJAN created HUDI-279:
---------------------------------------

             Summary: Regression in Schema Evolution due to PR-755
                 Key: HUDI-279
                 URL: https://issues.apache.org/jira/browse/HUDI-279
             Project: Apache Hudi (incubating)
          Issue Type: Bug
          Components: Common Core
            Reporter: BALAJI VARADARAJAN
             Fix For: 0.5.0


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? 
 
Caused by changes in :
