bq. StreamCapabilities.StreamCapability isn't public
I feel that it should be public. Will file a new JIRA for it.
{quote}
In the future, please atleast wait until your proposed JIRA actually lands. I'm
not sure I agree with this assertion that it should be public.

bq. Do all outputstreams returned from FileSystem implement StreamCapabilities?
I think they are going to support it, as WIP in HADOOP-14402.
{quote}
Even if/when HADOOP-14402 completes, there's nothing that requires an
outputstream to implement the interface right? so third party implementations
might not do so. We should call this out in the docs.
