Hudson commented on YARN-8206: ------------------------------ SUCCESS: Integrated in Jenkins build Hadoop-trunk-Commit #14250 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/14250/]) YARN-8206. Sending a kill does not immediately kill docker containers.

However, they should actually be separate. When YARN > sends a SIGKILL to a process, it means for it to die immediately and not sit > around waiting for anything. This ensures an immediate reclamation of > resources. Additionally, if a SIGTERM is sent before the SIGKILL, the task > might not handle the signal correctly, and will then end up as a failed task > instead of a killed task. This is especially bad for preemption. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
