Is it possible to deploy multiple timeline servers within a HDP 2.6.2 cluster?

Is it possible to deploy multiple timeline servers within a HDP 2.6.2 cluster?

New Contributor

I am trying to complete the installation of HCP 1.3.0 on an existing Ambari-managed cluster. I am using Ambari 2.5.2.0 and HDP 2.6.2.0, and one host within the cluster is running the Timeline server component.

The following documentation indicates that I need multiple slave nodes running the Timeline server:

https://docs.hortonworks.com/HDPDocuments/HCP1/HCP-1.3.0/bk_installation/content/specifications_for_...

However, I do not see any options within Ambari for deploying additional Timeline server components. Is it actually possible to deploy multiple instances of the Timeline server?

Hi @Evan Tattam

I don't think multiple YARN ATS are currently supported by the Apache Yarn project just yet, it is likely a roadmap feature. https://hadoop.apache.org/docs/r2.7.3/hadoop-yarn/hadoop-yarn-site/TimelineServer.html

I would assume it is a documentation issue for now and proceed with the remainder of the components. I'll follow up internally.
