[jira] [Commented] (HDDS-40) Separating packaging of Ozone/HDDS
from the main Hadoop
[ https://issues.apache.org/jira/browse/HDDS-40?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16470569#comment-16470569 ]

----------------------------------
Patch is uploaded. I tested it with docker-compose in the dist project and with the acceptance tested. Both worked well.

> According to the community vote, Ozone/Hdds release cycle should be independent from the Hadoop release cycle.
> To make it possible we need a separated ozone package.
> *The current state:*
> We have just one output tar/directory under hadoop-dist (hadoop-3.2.0). It includes all the hdfs/yarn/mapreduce/hdds binaries and libraries. (Jar files are put in separated directory).
> The hdds components and hdfs compobebts all could be started from the bin.
> *Proposed version*
> Create a sepearated hadoop-dist/ozone-2.1.0 which contains only the hdfs AND hdds components. Both the hdfs namenode and hdds datanode/scm/ksm could be started from the ozone-2.1.0 package.
> Hdds packages would be removed from the original hadoop-3.2.0 directory.
> This is a relatively small change. On further JIRAs we need to :
> * Create a shaded datanode plugin which could be used with any existing hadoop cluster
> * Use standalone ObjectStore/Ozone server instead of the Namenode+Datanod plugin.
> * Add test cases for both the ozone-only and the mixed clusters (ozone + hdfs)
