@Sami Ahmad

The issue is happening as has_key has been removed starting from Python3.

https://docs.python.org/3.1/whatsnew/3.0.html#builtins

To solve the issue, edit yarn-utils.py to change the below lines and see if it helps:-

if (reservedStack.has_key(memory)):

if (memory in reservedStack 😞

if (reservedHBase.has_key(memory)):

if (memory in reservedHBase):
