[jira] [Created] (YARN-3115) Work-preserving restarting of per-node aggregator

Zhijie Shen created YARN-3115:
---------------------------------

             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.
