Description

In scheduleer/objects/application.go, the IsReservedOnNode() function uses strings.HasPrefix to determine if a reservation belongs to a particular node. In the case where a node name is a prefix of another node (for example: node1 and node10), this can lead to application reservations stalling because the wrong node is chosen.
