    hadoop is dependant on having a whoami binary. I never really
    understood this it makes problems on windows as well I am not sure if
    you can specify the user. I would suggest creating your own whoami
    shell script and make it match the linux whoami output.

    conf.set ("hadoop.job.ugi", "hadoop,hadoop");

    did the trick for me in some unit tests i am writing. I still have problem
    running a MiniDFSCluster of my own.

    I guess that, with 0.16.1, setting this on any Windows installation would be
    mandatory.

    This prevents UnixUserGroupInfo to try to run 'whoami' and try to get groups
    membership information.

    I think it would be more portable to use System.getProperty ("user.name")
    than executing whoami.

    The group problem stays ... execing "bash -c groups" can not be stated as
    portable :-)

    Erwan

    2008/3/18 Eddie C <edlinuxguru@gmail.com>:
    hadoop is dependant on having a whoami binary. I never really
    understood this it makes problems on windows as well I am not sure if
    you can specify the user. I would suggest creating your own whoami
    shell script and make it match the linux whoami output.
