Subject [jira] [Updated] (YARN-5189) Make HBaseTimeline[Reader|Writer]Impl default and move FileSystemTimeline*Impl
Date Thu, 02 Jun 2016 16:29:59 GMT

     [ https://issues.apache.org/jira/browse/YARN-5189?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joep Rottinghuis updated YARN-5189:
-----------------------------------
    Attachment: YARN-5189-YARN-2928.04.patch

Oops, missed the property rename in yarn-default.xml

[~vrushalic] note that I clarified the description in
{code}
  <property>
	<description>
	The setting that controls how long the final value
	of a metric of a completed app is retained before merging into
	the flow sum. Up to this time after an application is completed
	out-of-order values that arrive can be recognized and discarded at the
	cost of increased storage.
	</description>
	<name>yarn.timeline-service.hbase.coprocessor.app-final-value-retention-milliseconds
	</name>
    <value>259200000</value>
  </property>
{code}
Could you please read to confirm this is an accurate statement?

> [~naganarasimha_gr@apache.org] questioned whether it made sense to default to an implementation
that doesn't support all functionality.
> [~sjlee0] opened YARN-5174 to track updating the documentation for ATS to reflect the
default shifting to the fully functional HBase implementation.
> It makes sense to remove a partial implementation, but on the other hand it is still
handing in testing. Hence this jira to move the file based implementations to the test package
and to make the HBase impls the default.
