Actually, this issue found in 2.6.0-cdh5.4.7.
I think the cause is that we modify {{Resouce}} while we are sorting
{{runnableApps}}.
{code:title=FSLeafQueue.java}
Comparator comparator = policy.getComparator();
writeLock.lock();
try {
Collections.sort(runnableApps, comparator);

public int compare(Schedulable s1, Schedulable s2) {
..
s1.getResourceUsage(), minShare1);
boolean s2Needy = Resources.lessThan(RESOURCE_CALCULATOR, null,
s2.getResourceUsage(), minShare2);
minShareRatio1 = (double) s1.getResourceUsage().getMemory()

minShareRatio2 = (double) s2.getResourceUsage().getMemory()

{{getResourceUsage}} will return current Resource. The current Resource is
