Summary: Separating packaging of Ozone/HDDS from the main Hadoop
Key: HDDS-40
URL: https://issues.apache.org/jira/browse/HDDS-40
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Elek, Marton
Assignee: Elek, Marton
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)
