Can you please check if you have sufficient resources available in YARN cluster to initiate containers? Take a look at RM UI.

I had the same issue and noticed that Yarn Memory was at 89%. I shutdown the VM and restarted. Yarn Memory was at 58%. I ran the table creation script - this time it ran. I checked Yarn Memory after the table was created - it had dropped to 11%.

So, Yarn Memory (under Dashboard) was at 89%. I shutdown the VM and restarted. Yarn Memory was at 58% before I started running the script to create geolocation table. This time a Tez session was created and the ORC table was created as well. I checked Yarn Memory after the table was created, it dropped to 11%.
