In HDP 3.0, yarn has a new implementation of Timeline server called Timeline server v2 (previouly timeline 1.5 was used).

TS v2 uses HBase for storing the information of all the applications. TS v2 will be started either as a system service (which is a yarn application) or in embedded mode ( runs a standalone hbase server) based on the resources. If the cluster has enough resources it will be started as a system service or yarn application which is true in your case.

You can check the config ( is_hbase_system_service ) to check if is running as a yarn application or in standalone mode.

You can read more about timeline server 2.0 here

Its a service that's running, not a job. So avoid killing it.
