Subject [jira] [Commented] (HDFS-12251) Add document for StreamCapabilities
Date Fri, 04 Aug 2017 18:57:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16114828#comment-16114828

Sean Busbey commented on HDFS-12251:

bq. StreamCapabilities.StreamCapability isn't public

I feel that it should be public. Will file a new JIRA for it.


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.

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.
