      We are releasing the alpha2 version of a major revision of YARN Timeline Service: v.2. YARN Timeline Service v.2 addresses two major challenges: improving scalability and reliability of Timeline Service, and enhancing usability by introducing flows and aggregation.

      YARN Timeline Service v.2 alpha1 was introduced in 3.0.0-alpha1 via YARN-2928.

      YARN Timeline Service v.2 alpha2 is now being provided so that users and developers can test it and provide feedback and suggestions for making it a ready replacement for Timeline Service v.1.x. Security is provided via Kerberos Authentication and delegation tokens. There is also a simple read level authorization provided via whitelists.

      Some of the notable improvements since alpha-1 are:
      - Security via Kerberos Authentication and delegation tokens
      - Read side simple authorization via whitelist
      - Client configurable entity sort ordering
      - New REST APIs for apps, app attempts, containers, fetching metrics by timerange, pagination, sub-app entities
      - Support for storing sub-application entities (entities that exist outside the scope of an application)
      - Configurable TTLs (time-to-live) for tables, configurable table prefixes, configurable hbase cluster
      - Flow level aggregations done as dynamic (table level) coprocessors
      - Uses latest stable HBase release 1.2.6

      More details are available in the [YARN Timeline Service v.2](./hadoop-yarn/hadoop-yarn-site/TimelineServiceV2.html) documentation.

      Description

      This is an umbrella JIRA for the alpha 2 milestone for YARN Timeline Service v.2.

      This is developed on feature branches: YARN-5355 for the trunk-based development and YARN-5355-branch-2 to maintain backports to branch-2. Any subtask work on this JIRA will be committed to those 2 branches.
