Subject [jira] [Commented] (YARN-5304) Ship single node HBase config option with single startup command
Date Wed, 13 Jul 2016 21:37:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-5304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15375807#comment-15375807

Karthik Kambatla commented on YARN-5304:
----------------------------------------

I spoke to [~esteban] about this. In his opinion, the minicluster approach (master, RS etc.
in a single process) is discouraged. I am assuming the goal is to do a pseudo-distributed
setup of HBase - Master and RegionServer in different processes.

> 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.
