      Description

      This error message was printed during an Express upgrade to HDP-2.5.3.0.

      Traceback (most recent call last):

      File "/usr/lib/python2.7/_strptime.py", line 325, in _strptime
      (data_string, format))
      ValueError: time data '2016-12-19 22:37:33' does not match format '%Y-%m-%d %H:%M:%S.%f'

      Doing some digging, the /usr/lib/python2.6/site-packages/resource_management/libraries/functions/security_commons.py does not handle non millisecond timestamps (line 205).

      The timestamp it is trying to analyse here is the /var/lib/ambari-agent/tmp/kinit_executor_cache/<<hash(hive.service.keytab|hive.principal.name)>>. The timestamp within this file matches that of the error: “'2016-12-19 22:37:33'” – which contains no miliseconds. There are other files in this directory all of which have timesstamps with miliseconds.
