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.

The reserved container on the node of reserve proposal will be checked only for
first-reserve container, not for the re-reserve container.
We could check reserved container on this node with re-reserve container to
avoid this problem.
