> DB purge logic is wrong
> -----------------------
>
> Key: AMBARI-25614
> URL: https://issues.apache.org/jira/browse/AMBARI-25614
> Project: Ambari
> Issue Type: Bug
> Reporter: ramkrishna.s.vasudevan
> Priority: Major
>
> While purging the DB, we get the
> {code}
> // find task ids using request stage ids
> Set<Long> taskIds =
> hostRoleCommandDAO.findTaskIdsByRequestStageIds(requestStageIds);
> // find host task ids, to find related host requests and also to remove
> needed host tasks
> final Set<Long> hostTaskIds = findHostTaskIds(taskIds);
> // find host request ids by host task ids to remove later needed host
> requests
> final Set<Long> hostRequestIds = findHostRequestIds(hostTaskIds);
> final Set<Long> topologyRequestIds =
> findTopologyRequestIds(hostRequestIds);
> {code}
> The hostRequestIds are already got from the topology_host_task table. Those
> hostRequestIds are now used to find the topologyrequestIds. Internally those
> should be got from the topology_logical_request table. But we instead again
> go to the topology_host_task table.
> Here what evern toplogyRequestIDs we get do not match with the actual
> Topology_requests. Hence the delete fails saying no such requestID found.
