------------------------------

             Summary: ambari_server/utils.py should be able to parse version with postfix text
                 Key: AMBARI-10968
                 URL: https://issues.apache.org/jira/browse/AMBARI-10968
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Di Li
            Assignee: Di Li


Apache ambari 2.0 has version "2.0.0" in the version file "/var/lib/ambari-server/resources/version". 

Since ambari is open source, it can be built with version information that has digits plus postfix like "2.0.0._MyCompany" in the version file "/var/lib/ambari-server/resources/version"

This postfix text causes the "ambari-server upgrade" cmd to fail with an int parser err thrown from the python script
