> The NPE happens where there is a node in cluster becomes unhealthy, and
> scheduler removes them from internal data structure. However, when the node
> heartbeats and scheduler tries to search for this node, and try to operate on
> it, it gets nullPointerException there. Here is the code snippet where this
> is causing NPE:
> SchedulerNode node = getSchedulerNode(nm.getNodeID());
> the node object is Null causing the Null pointer exception.
> Here is the RM log for caused exception:
> 15/10/06 09:18:09 INFO handlers.ResourceOffersEventHandler: Offer not
> sufficient for task with, cpu: 4.4, memory: 5504.0, spindles: 4.0, ports: 996
