Subject [jira] [Commented] (YARN-4455) Support fetching metrics by time range
Date Mon, 11 Jul 2016 18:09:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15371311#comment-15371311

Varun Saxena commented on YARN-4455:
------------------------------------

[~jrottinghuis]
This is to fetch metrics in a time series within a specific time range. For instance, if an
application runs from 11:00 am to 11:45 am and user wants to see a specific metric as a time
series from 11:20 am to 11:40 am only (maybe to debug some issue). This was the use case I
had in mind.
We can use Scan#setColumnFamilyTimeRange which I think is available from HBase 1.2 onwards.
I have linked the relevant HBase JIRA here as well.
