[jira] [Commented] (HDFS-7694) FSDataInputStream should support "unbuffer"

    [ https://issues.apache.org/jira/browse/HDFS-7694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14308531#comment-14308531 ]

------------------------------

Hi Colin, could you please re-base the patch?
One question, in what cases, user needs to unbuffer instead of closing the stream?

> For applications that have many open HDFS (or other Hadoop filesystem) files, it would be useful to have an API to clear readahead buffers and sockets.  This could be added to the existing APIs as an optional interface, in much the same way as we added setReadahead / setDropBehind / etc.
