> There seems to be an issue with pre-emption when using node labels with queue
> priority.
> Test configuration:
> queue A (capacity=50, priority=1)
> queue B (capacity=50, priority=2)
> both have accessible-node-labels set to x
> A.accessible-node-labels.x.capacity = 50
> B.accessible-node-labels.x.capacity = 50
> Along with this pre-emption related properties have been set.
> Test steps:
> - Set NM memory = 6000MB and containerMemory = 750MB
> - Submit an application A1 to B, with am-container = container =
> (6000-750-1500), no. of containers = 2
> - Submit an application A2 to A, with am-container = 750, container = 1500,
> no of containers = (NUM_NM-1)
> - Kill application A1
> - Submit an application A3 to B with am-container=container=5000, no. of
> containers=3
> - Expectation is that containers are pre-empted from application A2 to A3
> but there is no container pre-emption happening
> Container pre-emption is stuck with the message in the RM log,
> {noformat}
