Subject [jira] [Updated] (YARN-6528) Add JMX metrics for Plan Follower and Agent Placement and Plan Operations
Date Mon, 08 May 2017 18:39:04 GMT

     [ https://issues.apache.org/jira/browse/YARN-6528?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Po updated YARN-6528:
--------------------------
    Attachment: YARN-6528.v001.patch

YARN-6528.v001.patch adds metric details to the ReservationSystem, and abstracts common functionality
between AlignedPlannerWithGreedy and GreedyReservationAgent. Other implementations of ReservationAgent
are not included in the patch because the other implementations are used within the AlignedPlannerWithGreedy
and GreedyReservationAgent.

> YARN-1051 introduced a ReservationSytem that enables the YARN RM to handle time explicitly,
i.e. users can now "reserve" capacity ahead of time which is predictably allocated to them.
In order to understand in finer detail the performance of Rayon, YARN-6528 proposes to include
JMX metrics in the Plan Follower, Agent Placement and Plan Operations components of Rayon.
