Review comment:
Update the code to try to use the existing schema map to get the schema.
But if there is no schema in schema map, which means we don't register the
source table and not maintain the latest schema, we will still fetch from hive
to make sure we can always have the latest schema

> Sometime we need the avro schema in place even for ORC tables, we have that
> information in ingestion job but not for compaction job. And it's hard to get
> the avro schema from orc file itself, so we want to support schema source db,
> so that we can fetch the schema from source db where ingestion job registers
> to.
