-----------------------------------
The changes are done for master / Hudi 1.0. We'll discuss if we want to
cherry-pick the change back to Hudi 0.x releases separately.

> As of today, writing a partitioned table with CustomKeyGenerator requires
> write config of the partition field types (they are not stored as a table
> property). CustomKeyGenerator requires partition keys to be in the format of
> {{field:type}} (e.g. {{column1:SIMPLE}} ). However, only the field names are
> stored in {{hoodie.properties}} file. We need to store the field types too
> so that without the write config, the writer configure the correct partition
> field name and type in Spark datasource and SQL DML writes.
