Subject [jira] [Commented] (YARN-4905) Improve Yarn log Command line option to show log metadata
Date Mon, 18 Apr 2016 19:44:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-4905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15246395#comment-15246395

Vinod Kumar Vavilapalli commented on YARN-4905:

Thanks for working on this [~xgong], this is really useful!

Few comments on the patch:
 - Instead of "-ls", let's call it "--info" or "--show_meta_info"? /cc [~vvasudev]
 - Can you paste sample outputs here?
 - I think we should also have a "--list-nodes" option at the app-level to only show the list
of nodes where the app ran.
    -- This can be used to know which nodes could successfully aggregate logs.
    -- Long term, I think this should also get linked into "yarn application -status" for
that command to also perhaps print the info about logs.
 - Test-case: Don't use PBImpl objects (like ContainerIdPBImpl) directly.
