Subject [jira] [Commented] (YARN-1001) YARN should provide per application-type and state statistics
Date Thu, 08 Aug 2013 07:16:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-1001?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13733219#comment-13733219

Zhijie Shen commented on YARN-1001:
-----------------------------------

[~srimanth.gunturi], let me reword the requirement. Giving some application types and states,
Ambari wants to categorize the applications into the buckets of all combinations of these
application types and states, and count the number of the applications in each bucket. For
example, users want to know the number of the applications of three application types: type1,
type2, and type3, and two states: state1 and state2. Assume RM has 5 applications: app1(type1,
state1), app2(type2, state1), app3(type2, state1), app4(type2, state2), app5(type3, state1).
The users will get the following statistics:

[type1, state1]: 1
[type1, state2]: 0
[type2, state1]: 2
[type2, state2]: 1
[type3, state1]: 1
[type3, state2]: 0

Is this exactly what Ambari wants?

> In Ambari we plan to show for MR2 the number of applications finished, running, waiting,
etc. It would be efficient if YARN could provide per application-type and state aggregated
counts.
