[~Sreeram], there is a problem caused by this issue. Except the Java's
LinkedBlockingQueue, the other queue implementations like
BoundedPriorityBlockingQueue and AdaptiveLifoCoDelCallQueue don't implement the
method
{code:java}
public Iterator iterator()
{code}
this will cause a UnsupportedOperationException exception in
getCallQueueInfo(). Which can be easily be reproduced by the UT
testCallQueueInfo while adding a conf
{code}
conf.set("hbase.ipc.server.callqueue.type", "deadline");
{code}
{code}
java.lang.UnsupportedOperationException
