  • #43425

    Hi guys,
    I am learning something about hadoop, hdfs and other tools. I wrote some examples. However I cannot read any file from HDFS. I get this error.
    InvocationTargetException: Failed on local exception java.io.IOException: Response is null; Host Details : local host is : “sandbox/”;
    destination host is “sandbox:8020”

    My argument is : “hdfs://” is it wrong?

    Thanks for any helps/ideas.
