Subject [jira] [Commented] (YARN-6177) Yarn client should exit with an informative error message if an incompatible Jersey library is used at client
Date Thu, 16 Feb 2017 03:12:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15869045#comment-15869045

Weiwei Yang commented on YARN-6177:
-----------------------------------

Hi [~gtCarrera9]

Yes, 2 approaches

# Set {{yarn.timeline-service.client.best-effort}} to {{true}} with this patch, so yarn client
doesn't treat such failure as a fatal error. Default value is false, so user always hits the
error with the prompted message at first time.
# Set {{yarn.timeine-service.enabled}} to {{false}} to disable timeline service from client
side config. 

I was suggesting to use #1 because it literally explains the work around better. Disable timeline
service is a bit confusing because this property is more like a server side config.

timeline service instead of disabling for them.
