First of all thank you very much for proving the quickstart vm. It allowed me to have a nice first insight into the technologies i am planning to use.
There are some issues that don't let me progress further in the turorials:
http://quickstart.cloudera/#/go_grid is completely empty. No information given.
The example also contains a wrong command since the home folder as root is not cloudera:
[firstname.lastname@example.org ~] hadoop fs -copyFromLocal ~/*.avsc /user/examples/
this should actually be
[cloudera@quickstart ~]$ hadoop fs -copyFromLocal ~/*.avsc /user/examples/
I cannot execute any queries in Impala, the queries time out. The same queries work fine in Hive. I already tried changing the timeout in beeswax as suggested after googling.
The only thing that did was to display the timeout a bit later. I checked the steps multiple times, can't spot any issue with the tutorial.

Thanks for reporting your issues, Thorsten.
>> http://quickstart.cloudera/#/go_grid is completely empty. No information given.
Where are you seeing this URL? It's used in a similar tutorial when you spin up a Cloudera cluster on GoGrid, but it should not show up in the tutorial when you view it on Cloudera Live, and I can't find it in my copy of the VM. In any case, you do not need any information from that page if you're using the VM - it just walks you through finding your SSH credentials / root password on GoGrid. In the VM, you can SSH if you want (root password is cloudera), but you can also just open a terminal directly.
>> The example also contains a wrong command since the home folder as root is not cloudera:
Thanks for pointing that out - I'll get it fixed for the next VM. That's actually the hostname of the machine and it's not meant to have the domain included - not the home directory.
>> I cannot execute any queries in Impala, the queries time out.
I'm not able to reproduce this problem. Could you verify that the Impala services are running correctly? e.g.
service impala-server status
service impala-state-store status
service impala-catalog status
If all services are running, I'd suggest you check the logs in /var/log/impala or /var/log/hue and see if you can find any helpful error messages about exactly what's timing out or failing.

Hell and thank you for the answers.
The link can be found on http://quickstart.cloudera/#/tutorial/ingest_structured_data under "Your Cloudera Cluster"
I restarted all the services and the query seems to be running getting another error on the Results tab:
Fetching results ran into the following error(s):
Error reading from HDFS file: hdfs://quickstart.cloudera:8020/user/hive/warehouse/tokenized_access_logs/000000_0 Error(255): Unknown error 255
Checking the configuration gives me this:
Potential misconfiguration detected. Fix and restart Hue.
