Eric Payne commented on MAPREDUCE-7079:
---------------------------------------
Hi [~ahussein]. I'm still working my way through the comments above and trying
to understand the code. However, I have one comment to start with.
In {{JobHistory}}, the old code looks like it loops for about 10 seconds before
the timeout kicks in (unless the shutdown completes or it's interrupted):
{code:title=JobHistory#serviceStop}
while (!scheduledExecutor.isShutdown()
&& System.currentTimeMillis() > currentTime + 1000l && !interrupted) {
try {
Thread.sleep(20);
{code}
However, if I'm reading this right, the new code has a timeout of 1 second:
{code:title=JobHistory#serviceStop}
int retryCnt = 50;
try {
while (!scheduledExecutor.awaitTermination(20,
TimeUnit.MILLISECONDS)) {
if (--retryCnt == 0) {
{code}
{{20ms timeout X 50 retries = 1000 ms}}
