Sangjin Lee commented on YARN-5304:
-----------------------------------
Thanks for the summary [~vrushalic]. It is a good summary of the discussion.
Just to add a couple of more fine points,
- we would package this timeline service specific hbase configuration file in
hadoop
- this file would now be required to be present; that would also entail making
{{TIMELINE_SERVICE_HBASE_CONFIGURATION_FILE}} a required config and the file it
points to required, or
{{HBaseTimelineStorageUtils.getTimelineServiceHBaseConf()}} should fail
- bringing up hbase would require using this config file via the {{--config}}
option (i.e. {{"hbase --config ...}})
> Ship single node HBase config option with single startup command

> URL: https://issues.apache.org/jira/browse/YARN-5304
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Affects Versions: YARN-2928
> Reporter: Joep Rottinghuis
> Assignee: Vrushali C
> Labels: YARN-5355, yarn-5355-merge-blocker
>
> For small to medium Hadoop deployments we should make it dead-simple to use
> the timeline service v2. We should have a single command to launch and stop
> the timelineservice back-end for the default HBase implementation.
> A default config with all the values should be packaged that launches all the
> needed daemons (on the RM node) with a single command with all the
> recommended settings.
> Having a timeline admin command, perhaps an init command might be needed, or
> perhaps the timeline service can even auto-detect that and create tables,
> deploy needed coprocessors etc.
> The overall purpose is to ensure nobody needs to be an HBase expert to get
> this going. For those cluster operators with HBase experience, they can
> choose their own more sophisticated deployment.
