    Hi,

    I am getting error when running a map reduce job from command line, which reads the file content and writes it to a table.
    The job is running fine from Eclipse.
    I am getting below error when running from CMD prompt.

    Thanks Dave for your quick response.
    We are able resolve the issue, The reason for job failure is due to the first Exception (“Shell Exception”).

    Hi Samba,

    In your program you have not specified the Output directory, please set the following and try again:

    HFileOutputFormat.setOutputPath(conf, new Path(<YOUR_LOCATION>));

    Thanks

    Dave
