I am attempting to connect Tableau to the HortonWorks Hadoop sandbox as described here: Tableau is able to see the virtual server as a data source, and it accurately lists the available Schemas and Tables.

However, when attempting to select any table or preview its data, it displays an error popup that 'An error has occurred while loading the data. No such table [default].[tablename]' where the default is the schema and tablename is the name of the table I'm attempting to view.

Here is what comes back when I run ifconfig from the Terminal window in the VM sandbox. Tableau is connecting to the VM via

eth3      Link encap:Ethernet  HWaddr 00:0C:29:EB:B9:DC  

          inet addr:  Bcast:  Mask:

          inet6 addr: fe80::20c:29ff:feeb:b9dc/64 Scope:Link


          RX packets:42011 errors:0 dropped:0 overruns:0 frame:0

          TX packets:9750 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000 

          RX bytes:15123871 (14.4 MiB)  TX bytes:4019795 (3.8 MiB)

lo        Link encap:Local Loopback  

          inet addr:  Mask:

          inet6 addr: ::1/128 Scope:Host

          UP LOOPBACK RUNNING  MTU:65536  Metric:1

          RX packets:5185579 errors:0 dropped:0 overruns:0 frame:0

          TX packets:5185579 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:0 

          RX bytes:2054785522 (1.9 GiB)  TX bytes:2054785522 (1.9 GiB)

The guide states Enter the IP address of the Sandbox VM (typically which is different.

Is this IP difference the source of the issue or is there something else I've overlooked? I'm assuming that since it can see the schema and tables that this wouldn't matter.

Turns out this was a permissions issue which I was able to resolve by following this guide:

However, everywhere I was told to input localhost, such as when accessing Ambari, I had to replace localhost with which I mentioned above is the IP I saw when executing ifconfig in the terminal.

Also, in step 1 of the guide, there should not be any spaces in the file paths that were provided.
