Subject [jira] [Commented] (HDFS-497) One of the DFSClient::create functions ignores parameter
Date Tue, 27 Sep 2011 16:57:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13115705#comment-13115705

Uma Maheswara Rao G commented on HDFS-497:

Hi Bill,

Are you talking about below code snippet in DFSClient?
public OutputStream create(String src, boolean overwrite) 
      throws IOException {
    return create(src, overwrite, dfsClientConf.defaultReplication,
        dfsClientConf.defaultBlockSize, null);


This can be fixed by simply passing the correct argument.{quote}

Here actually, when client doesn't want to see any progress, then why we need to pass progressible?

See the javadoc of Progressable

 * <p>Clients and/or applications can use the provided <code>Progressable</code>
 * to explicitly report progress to the Hadoop framework. This is especially
 * important for operations which take an insignificant amount of time since,
 * in-lieu of the reported progress, the framework has to assume that an error
 * has occured and time-out the operation.</p>{code}

in my opinion, when client invokes create api without progressable perameter, then we need
to pass it as null. I feel this is correct behavior. Please correct me if i understood wrongly.
