>
> When an AM is assigned a FAILED_MAP (priority = 5) container on a nodemanager
> which it has blacklisted - it tries to
> find a corresponding container request.
> This uses the hostname to find the matching container request - and can end
> up returning any of the ContainerRequests which may have requested a
> container on this node. This container request is cleaned to remove the bad
> node - and then added back to the RM 'ask' list.
> The AM cleans the 'ask' list after each heartbeat - The RM Allocator is still
> aware of the priority=5 container (in 'remoteRequestsTable') - but this never
> gets added back to the 'ask' set - which is what is sent to the RM.
