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

             Summary: Installing Repo Packages needs to be more robust to handle the actual
version installed when the script is killed because of a timeout
                 Key: AMBARI-12083
                 URL: https://issues.apache.org/jira/browse/AMBARI-12083
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
            Priority: Critical
             Fix For: 2.1.0


When installing bits of a new repo to perform an RU, if the repo version does not contain
a build number, then the actual_version has to be calculated.
The problem is that this information can only be retrieved by calculating the delta of the
versions when calling "hdp-select versions", so the only the first time will return a value.
If the script is killed, then the actual_version will never be calculated and returned to
the server.

For this reason, the package installer must tolerate receiving a SIGINT or SIGTERM, and calculate
the actual_version. Further, it helps to store it in a file, in case that the response or
something upstream results in another failure.
