Kihwal Lee commented on MAPREDUCE-4387:
---------------------------------------
{{EventProcessor#stop()}} is setting {stopped} to true before interrupting the
thread. So we could just add one more condition and let it terminate normally.
{code}
while (!stopped && !Thread.currentThread().isInterrupted()) {
try {
event = eventQueue.take();
} catch (InterruptedException e) {
LOG.error("Returning, interrupted : " + e);
return; // TODO: Kill RM.
}
try {
scheduler.handle(event);
} catch (Throwable t) {
+ if (stopped) {
+ LOG.warn("Exception during shutdown: ", t);
+ break;
+ }
LOG.fatal("Error in handling event type " + event.getType()
+ " to the scheduler", t);
if (shouldExitOnError
&& !ShutdownHookManager.get().isShutdownInProgress()) {
LOG.info("Exiting, bbye..");
System.exit(-1);
}
}
}
{code}
