Subject [jira] [Commented] (YARN-5299) Log Docker run command when container fails
Date Thu, 14 Jul 2016 06:15:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-5299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15376387#comment-15376387

Vinod Kumar Vavilapalli commented on YARN-5299:

Can we print similar logging for other commands like signalContainer?

For launch failure, does it make sense to expose this full-command further up into the container-diagnostics?

Not related to this patch, but another thing that is a little overwhelming is the following
in DelegatingLinuxContainerRuntime
    if (LOG.isInfoEnabled()) {
      LOG.info("Using container runtime: " + runtime.getClass()
Make it debug only?

> It's useful to have the docker run command logged when containers fail to help debugging.
