Subject [jira] [Commented] (HDFS-12260) StreamCapabilities.StreamCapability should be public.
Date Wed, 16 Aug 2017 01:04:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16128172#comment-16128172
] 

Andrew Wang commented on HDFS-12260:
------------------------------------

Are we changing hasCapability as part of this? Part of why it's string-typed is so we can
query for unknown capabilities, which lets other subclasses add new capabilities without modifying
the core hadoop code.

> Client should use {{StreamCapability}} enum instead of raw string to query the capability
of an OutputStream, for better type safety / IDE supports and etc.
