Hi Artem - I appreciate you looking into this. I checked the directories and permissions and they were all in order. The issue turned out to be yarn and mapreduce needing restarts.

From looking at your RM UI it sure looks like both of these jobs are basically fighting each other to get running. Meaning, the AppMaster containers are running, but they can't get anymore more containers to be run from YARN. My recommendation would be to give the VM 10GB of memory (that's how I run it on my 16GB laptop) when you restart it. I'd also try to run it from the command line just to take the Ambari View out of the picture, but if you want to run it in Ambari then kill any application via the RM UI that is around should it hang again. Good luck and happy Hadooping! ... View more
