> Reproduce this problem:
> 1. nm1 re-reserved app-1/container-X1 and generated reserve proposal-1
> 2. nm2 had enough resource for app-1, un-reserved app-1/container-X1 and
> allocated app-1/container-X2
> 3. nm1 reserved app-2/container-Y
> 4. proposal-1 was accepted but throw IllegalStateException when applying
> Currently the check code for reserve proposal in FiCaSchedulerApp#accept as
> follows:
> {code}
> // Container reserved first time will be NEW, after the container
> // accepted & confirmed, it will become RESERVED state
> if (schedulerContainer.getRmContainer().getState()
> == RMContainerState.RESERVED) {
> // Set reReservation == true
> reReservation = true;
> } else {
> // When reserve a resource (state == NEW is for new container,
> // state == RUNNING is for increase container).
> // Just check if the node is not already reserved by someone
> if (schedulerContainer.getSchedulerNode().getReservedContainer()
> != null) {
> if (LOG.isDebugEnabled()) {
> LOG.debug("Try to reserve a container, but the node is "
> + "already reserved by another container="
> + schedulerContainer.getSchedulerNode()
> .getReservedContainer().getContainerId());
> }
> return false;
> }
> }
> {code}
> The reserved container on the node of reserve proposal will be checked only
> for first-reserve container.
> We should confirm that reserved container on this node is equal to re-reserve
> container.
