vinoyang commented on FLINK-10114:
----------------------------------

[~kkl0u] In fact, I saw the PR of Parquet implementation FLINK-9753 by 
[~StephanEwen]. The main problem for Orc is that its API only supports building 
a Writer based on Path, but BulkWriter needs to rely on an FSDataOutputStream. 
There is an adaptation here (Parquet exposes a stream object called 
*PositionOutputStream*. Adaptation can be done relatively easily.). But as far 
as Orc is concerned, this adaptation is cumbersome.
