---------------------------
Summary: Provide new timeline plugin storage to support
fine-grained entity caching
Key: YARN-4265
URL: https://issues.apache.org/jira/browse/YARN-4265
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Li Lu
Assignee: Li Lu
To support the newly proposed APIs in YARN-4234, we need to create a new plugin
timeline store. The store may have similar behavior as the
EntityFileTimelineStore proposed in YARN-3942, but cache date in cache id
granularity, instead of application id granularity. Let's have this storage as
a standalone one, instead of updating EntityFileTimelineStore, to keep the
existing store (EntityFileTimelineStore) stable.
