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

             Summary: When querying host role command entities, the number of parameters should
be limited
                 Key: AMBARI-17449
                 URL: https://issues.apache.org/jira/browse/AMBARI-17449
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Daniel Gergely
            Assignee: Daniel Gergely
             Fix For: 2.4.0, 2.2-next, 2.5.0


In the case of a larger cluster, the number of host role commands can be high (magnitude of
thousands). Database servers usually have a limit on the number of parameters, so reaching
this limit causes a failure.

Paging should be introduced to have only a smaller number of parameters in a single query
and do multiple queries to obtain the final result.
