[jira] [Commented] (YARN-4759) Fix signal handling for docker
containers
[ https://issues.apache.org/jira/browse/YARN-4759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15376830#comment-15376830 ]
Shane Kumpf commented on YARN-4759:
-----------------------------------
It appears the jenkins slave failed during the precommit job. I'm also only showing the two previously called out checkstyle bugs when running locally, not three as shown above. Reattaching the same patch to rerun the jenkins job.

> The current signal handling (in the DockerContainerRuntime) needs to be revisited for docker containers. For example, container reacquisition on NM restart might not work, depending on which user the process in the container runs as.
