  File "./", line 701, in main
  File "./", line 144, in do_cleanup
    procList = proc_map.get(PROCESS_KEY)
AttributeError: 'NoneType' object has no attribute 'get'

And the OS I am using is Ubuntu 16.04.5 LTS.

@Arif Ishak

Which version of Ambari are you using ? Is it 2.7.0 / 2.7.1 ?

Looks like it might be related to :

Can you please try the same on Ambari 2.7.3 which is latest.

hi @Arif Ishak, did you solve this issue ? I have the same error and I can't find the solution.
