Description

For JSON, CSV and OldCsv, we already supported derive.schema=true to get the schema from table schema. But for Avro format, a user has to pass an Avro schema file or define the format schema explicitly via avro.schema.

We can think of if we can drop avro.schema and make derive.schema=true as the default behavior.
