> Previously, we remove the schema.literal for partition.  Because Avro schemas 
> should _only_ be defined at the table level. Hive overrides table properties 
> if the same property is defined on the partition. Defining them at the 
> partition level may lead to partitions with inconsistent schemas. And because 
> column metadata is calculated from schema.literal, so we remove the column 
> metadata as well.
> Then we encounter a problem that presto cannot read data from orc file. 
> Because ORC (and other Hive serdes) need metadata in the partitions so that 
> coercion can be done between a partition schema and the table schema.
> So we need to treat Avro and other formate separately to make sure hive 
> registration works well so that user can read right data from Presto.
