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 15:21:41 GMT

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

Hello [~jlowe]

Thanks for the input, it's quite helpful. Option #1 was not to change best-effort default
value, I meant to say with the patch provided in this ticket, user will be able to work around
this jar conflict problem if they want to set "yarn.timeline-service.client.best-effort" to
"true". If both of you think the best-effort property was not suitable to handle an error
like this, let me upload a new patch and just give the error message (suggest user to disable
timeline service to work around). Thanks you!
