    I cannot get past the initial PowerQuery Screen.
    Errors are:
    DataSource.Error: The remote name could not be resolved: ‘sandbox.hortonworks.com’ Details:

    I added an entry into my hosts file, that didn’t help.

    When I try to browse to the webHDFS screens I get:
    {"RemoteException":{"exception":"UnsupportedOperationException","javaClassName":"java.lang.UnsupportedOperationException","message":"op=NULL is not supported"}}

    Also when using the built in browser from I get:
    could not connect to

    Looks like an internal configuration error. Anyone out there resolve this?

    I had IIS 7 listening on port so I turned that off and reinitialized the Sandbox. I also added the for Sandbox.Hortonworks.com. I can continue the tutorial.

    Respected sir,
    suppose if I take web log data in my institute, how I have to pre-process and make it into .tsv.gz files.
    kindly give me solution so that it can be very useful for my research work.
