Looks like a good start! I will mark this PR WIP for now.
Is there a good first milestone we are targeting here? for e.g Write data using Spark Datasource and read via Hive, for COW tables.

is this something you have written from scratch? wondering if there is no built in way like parquet-avro to aid this conversion. Guess not?

if this code is borrowed or reused from somewhere else, then we would have to cite/credit the source

AFAIK @prashantwason @vingov are also interested in this. @manijndl7 are you still actively working on this? or do you mind if one of them take this across finish line/merge efforts? |
|
Yes, we are interested in ORC support. We have already started an internal project towards this end. |
|
@prashantwason please feel free to grab HUDI-57. |
|
Hi @vinothchandar , my progress is bit slow because of current project going on i would be happy if someone make it to the finish line |
|

|
