Hi  I am a new user and I've just installed virtual box and trying to run sandbox on my windows. I have not been able to use the software successfully. most times when I input localhost:1080 on my browser, I get 'error 540 bad Gateway'. when I don't get that, my first screen on Ambari shows that the running process wasn't successful as most items on the left panel have red warning signals and some numbered alerts. when I choose hive and try to restart all, it most times wont finish the process and I can't use the software. The picture below shows what my screen looks like when I try to get into Ambari.  I am a student and need to use the program for my learning and assessment in school.   Thank you   ... View more
