Subject [jira] [Commented] (YARN-5105) entire time series is returned for YARN container system metrics (CPU and memory)
Date Tue, 17 May 2016 21:34:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-5105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15287624#comment-15287624
] 

Varun Saxena commented on YARN-5105:
------------------------------------

How do we handle it ? Have an explicit limit from user or have an internal limit or a combination
of both (a default limit if no limit from user is specified) ?
Or go the time range way. Had raised YARN-4455 earlier wherein the idea was to trim the metric
result by time range.

> I see that the entire time series of the CPU and memory metrics are returned for the
YARN containers REST query. This has a potential of bloating the output big time.
