yarn.timeline-service.generic-application-history.max-applications does not effect

New Contributor

I config yarn.timeline-service.generic-application-history.max-applications to 100000, but it is does not work. While the ResourceManager UI still shows "showing 1 to 20 of 10,017 entries", and the max number of entries always under 10020.

I found the default value of this configuration is 10000.

yarn.timeline-service.generic-application-history.max-applicationsThe max number of applications could be fetched by using REST API or application history protocol and shown in timeline server web ui. Defaults to 10000.

The official document link is https://hadoop.apache.org/docs/r2.7.3/hadoop-yarn/hadoop-yarn-site/TimelineServer.html

My ambari version is 2.6.5.0-292, and the hadoop version is 2.7.3.2.6.5.0-292.

Would appreciate any help.
