Description

It seems that the default implementation classes of Orc today depend on Hadoop FS objects to write. This is not ideal for APIs that do not rely on Hadoop. For some context I was taking a look at adding support for Apache Beam, but Beam's API supports multiple filesystems with a more generic abstraction that relies on Java's Channels and Streams APIs and delegate directly to Distributed FS e.g. Google Cloud Storage, Amazon S3, etc. It would be really nice to have such support in the core implementation and to maybe split the Hadoop dependencies implementation into its own module in the future.
