---------------------------------

You already have done all the hard work of debugging etc. Would be great if you can provide the patch and get credit for the work.

> If the minimum idle timeout is 0, but the max is greater than 0, a random distribution should still be created for expiring session containers.  The offending code is in {{YarnTaskSchedulerService}} lines 991-993:
> {noformat}
> if (idleContainerTimeoutMin > 0) {
>     heldContainer.setContainerExpiryTime(getHeldContainerExpireTime(currentTime));
> }
> {noformat}
