Key: YARN-4190 URL: https://issues.apache.org/jira/browse/YARN-4190 Project: Hadoop YARN Issue Type: Improvement Components: fairscheduler Affects Versions: 2.7.1 Reporter: zhihai xu Assignee: zhihai xu Priority: Trivial
Add container information in FairScheduler preemption log to help debug. Currently the following log doesn't have container information {code} LOG.info("Preempting container (prio=" + container.getContainer().getPriority() + "res=" + container.getContainer().getResource() + ") from queue " + queue.getName()); {code} So it will be very difficult to debug preemption related issue for FairScheduler. Even the container information is printed in the following code {code} LOG.info("Killing container" + container + " (after waiting for premption for " + (getClock().getTime() - time) + "ms)"); {code} But we can't match these two logs based on the container ID. It will be very useful to add container information in the first log. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
