    If you want to login to the VM’s shell what account/password do you use?

    Yes, user sandbox could be used for running jobs.
    Or, you can use individual users for specific tasks (like user hbase for hbase work, hive for hive and pig, etc).
    each user have it’s own “home” folder in HDFS /user/, and all of them belongs top group hdfs.

    Hope this help.

    Or, maybe “sandbox” is the recommended user to do the stuff.

    Thanks Sasha. I see, so only the user hdfs has the permission to do the hdfs operations. Other than that, can we just use root user to do pig/hbase/hive things?

    Wei,
    If you need to log in to the Sandbox itself, username is root, password is hadoop
    the, you can do something like:
    su – hdfs -c “hadoop fs -ls /”

    etc.

    Thank you!

    What if we want to do everything on the command line? For example, do hadoop fs operations, run map/reduce jobs, compose java programs, run pig/hive scripts/commands..

    Does this sandbox support all the above operations? Can we assume this is a fully functional hadoop box besides the web interface? Thanks!

    For the developer type would you recommend me modifying the image you have and installing a development environment on this image? When I refer to dev environment I am referring to Gnome centos environment with Eclipse for Map/Reduce and R. What is your recommendation?

    Please note that when logging into root, there is no support for configuration or technical issues on the Sandbox.

    Confirmed.
    You do not need login in order to use browser based UI.
    If you need to log in to the Sandbox itself, username is root, password is hadoop

    no login required according to documentation:
