> Project: Apache Hudi
> Issue Type: Improvement

> Priority: Blocker
> Labels: pull-request-available

>
> We changed the format of partition field table config
> "{{{}hoodie.table.partition.fields{}}}" for custom keygen on master and Hudi
> 1.0. Hudi 1.0 reader should be able to read both 1.0 and 0.x tables with
> custom key generator and different partition field table config formats.
>
> For 0.x tables, we should consider both old format, i.e., 0.15.0 behavior
> where partition field type and timestamp configs maybe unknown for custom
> keygen, and the case where partition field type and timestamp configs are
> added.
> The PR also handles the logic where partition path field config
> `hoodie.datasource.write.partitionpath.field` is derived from existing table
> config so that it uses the custom keygen partition type when available.
