>             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.
