incoming data is empty
                 Key: HUDI-7201
                 URL: https://issues.apache.org/jira/browse/HUDI-7201

          Issue Type: Bug
          Components: spark, spark-sql

{code:java}
if (sourceSchema.getType() == Schema.Type.NULL || 
sourceSchema.getFields().isEmpty() || targetSchema.getFields().isEmpty()) {
  return sourceSchema;
} {code}
This will allow illegal schema evolutions if the previous commit was empty
