Karthik Kambatla commented on YARN-4756: ---------------------------------------- The patch seems reasonable to me. +1. Also, quite excited to see a +1 from Hadoop QA. Checking this in. > 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 > Attachments: YARN-4756.001.patch, YARN-4756.002.patch, > YARN-4756.003.patch, YARN-4756.004.patch, YARN-4756.005.patch > > > The startStatusUpdater 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
