---------------------------------
Summary: Reliable TimelineClient
Key: YARN-2521
URL: https://issues.apache.org/jira/browse/YARN-2521
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelineserver
Affects Versions: 2.5.0, 3.0.0
Reporter: Zhijie Shen
Assignee: Zhijie Shen
The timeline server is likely to be in outage. It would be beneficial if the
timeline client can cache the timeline entity locally after the application
pass it to the client, and before the client successfully hands it over to the
server.
To prevent the entity from being lost, we may want to persist it into the
secondary storage, such as HDFS and Leveldb.
