Sagar Sumit commented on HUDI-1842:
-----------------------------------
> table name has to match the table name as per hoodie.properties.
This is true otherwise the write will throw an exception as follows:
HoodieException: hoodie table with name hudi_trips_cow already exists at
file:/tmp/hudi_trips_cow
> [SQL] Spark Sql Support For The Exists Hoodie Table

>
> In order to support spark sql for hoodie, we persist some table properties to
> the hoodie.properties. e.g. primaryKey, preCombineField, partition columns.
> For the exists hoodie tables, these properties are missing. We need do some
> code in UpgradeDowngrade to support spark sql for the exists tables.
