jj updated OOZIE-3160:
----------------------
Description:
oozie process always consume high cpu. in my mechine,around 10%.
I check the source code，find take() method in PriorityDelayQueue class。
code:
{code:java}
public QueueElement<E> take() throws InterruptedException {
QueueElement<E> e = poll();
while (e == null) {
Thread.sleep(10);
e = poll();
}
return e;
}
{code}
i think it's the reason of this problem. it's keep while, not await.
