---------------------------------
Summary: Unnecessary wait in Node Status Updater during reboot
Key: YARN-4756
URL: https://issues.apache.org/jira/browse/YARN-4756
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Eric Badger
Assignee: Eric Badger
The Node Status Updater thread waits for the isStopped variable to be set to
true, but it is waiting for the next heartbeat. During a reboot, the next
heartbeat will not come and so the thread waits for a timeout. Instead, we
should notify the thread to continue so that it can check the isStopped
variable and exit without having to wait for a timeout.
