> org.apache.hadoop.gateway.ha.provider.impl.DefaultURLManager is not 
> thread-safe.
> Currently, only the "write" methods are subject to locking. Apparently, there 
> are some assumptions being made about the behavior of the underlying 
> ConcurrentLinkedQueue.
> For instance, if a thread is preempted in setActiveURL(String), and another 
> thread invokes getActiveURL(), the urls.peek() result could be incorrect.
