You must access the resource manager UI or look in the logs for what the query is doing.
Unfortunately HUE (the web interface) will not give you this information.
You will have to ssh into the machine – how good are your Linux skills?
You may want to start Ambari and go to 127.0.0.1:8080 (or whatever your sandbox IP is) and from there you can get to the ResourceManager UI to look at the job.
Can you paste your query here which you are doing?
Look in the hive logs on the sandbox and check the Yarn logs too.
