---------------------------------
Summary: Work-preserving restarting of per-node aggregator
Key: YARN-3115
URL: https://issues.apache.org/jira/browse/YARN-3115
Project: Hadoop YARN
Issue Type: Bug
Components: timelineserver
Reporter: Zhijie Shen
Assignee: Zhijie Shen
YARN-3030 makes the per-node aggregator work as the aux service of a NM. It
contains the states of the per-app aggregators corresponding to the running AM
containers on this NM. While NM is restarted in work-preserving mode, this
information of per-node aggregator needs to be carried on over restarting too.
