Subject [jira] [Created] (HDFS-7694) FSDataInputStream should support "unbuffer"
Date Wed, 28 Jan 2015 22:02:34 GMT
Colin Patrick McCabe created HDFS-7694:
------------------------------------------

             Summary: FSDataInputStream should support "unbuffer"
                 Key: HDFS-7694
                 URL: https://issues.apache.org/jira/browse/HDFS-7694
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.7.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


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.
