             Summary: Add some Abortable.abort() interface for streams etc which can be terminated
                 Key: HADOOP-16906
                 URL: https://issues.apache.org/jira/browse/HADOOP-16906
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs, fs/azure, fs/s3
    Affects Versions: 3.3.0
            Reporter: Steve Loughran


Some IO we want to be able to abort rather than close cleanly, especially if the inner stream is an HTTP connection which itself supports some abort() method. For example: uploads to an object where we want to cancel the upload without close() making an incomplete write visible.

Proposed: Add a generic interface which things like streams can implement
{code}
AbortableIO {
  public void abortIO() throws IOE;
}
{code}

+do for s3a output stream. I wouldn't do this a passthrough on FSDataOutputStream because we need to consider what expectations callers have of an operation being "aborted"
