> Administrator raised a update for queues through REST API, in RM parent queue
> is refreshing child queues through calling ParentQueue#reinitialize,
> meanwhile, async-schedule threads is sorting child queues when calling
> ParentQueue#sortAndGetChildrenAllocationIterator. Race condition may happen
> and throw exception as follow because TimSort does not handle the concurrent
> modification of objects it is sorting:
> {noformat}
> java.lang.IllegalArgumentException: Comparison method violates its general

> I think we can add read-lock for

> write-lock will be hold when updating child queues in
> ParentQueue#reinitialize.
