Questions About Event Listener For Yarn RM

[Herier chen <ch...@gmail.com>]

Hi Hadoop Experts,

Happy New Years!!

I know we have yarn RM restAPI to grab all the information about
applications.
<https://hadoop.apache.org/docs/r2.8.0/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Applications_API>

My question is does yarn RM provide any event listener for  app created,
killed, failed and finished?

Regards
Jessica Chen

Jessica,

Thank you for raising this. Currently there is no event listener, you can
only poll the REST API.
Please feel free to open a jira for this.

Best Regards,
Miklos
