Local variable 'response' referenced before assignment

[vishalvpv]

File "/var/lib/ambari-agent/cache/stacks/HDP/2.4/services/ZEPPELIN/package/scripts/master.py", line 230, in post_request

jsonresp = json.loads(response.decode('utf-8'))
UnboundLocalError: local variable 'response' referenced before assignment

Above assignment should only be done if exception does not occur.

I manually made the code change suggested here and then restarted the ambari-server to make it work.
