--------------------------------------
Summary: RMStateStore should trim down app state for completed
applications
Key: YARN-5028
URL: https://issues.apache.org/jira/browse/YARN-5028
Project: Hadoop YARN
Issue Type: Improvement
Components: resourcemanager
Affects Versions: 2.8.0
Reporter: Karthik Kambatla
RMStateStore stores enough information to recover applications in case of a
restart. The store also retains this information for completed applications to
serve their status to REST, WebUI, Java and CLI clients. We don't need all the
information we store today to serve application status; for instance, we don't
need the {{ApplicationSubmissionContext}}.
