             Summary: Need a robust check for the existence of a package
                 Key: AMBARI-12961
                 URL: https://issues.apache.org/jira/browse/AMBARI-12961
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.1.2


There is a problem in the way Ambari checks for existence of packages to skip
calls to install.

The string used to install usually has some wild-cards e.g. `zookeeper_2_2_*`.
If install is called using this string, it will pull in all packages that
satisfy the condition.

  * zookeeper_2_2_6_0_2800-server-3.4.6.2.2.6.0-2800
  * zookeeper_2_2_6_0_2800-3.4.6.2.2.6.0-2800

However, if "hadoop_2_2*" is installed first then it only pulls in
zookeeper_2_2_6_0_2800-3.4.6.2.2.6.0-2800. Existence of this package satisfies
the check if `zookeeper_2_2_*` is installed and thus
`zookeeper_2_2_6_0_2800-server-3.4.6.2.2.6.0-2800` does not get installed.

This resulted in <https://issues.apache.org/jira/browse/AMBARI-12874> where
"hdp-select set zookeeper-server VERSION" is not called as
zookeeper_2_2_6_0_2800-server-3.4.6.2.2.6.0-2800 never got installed.
