Subject [jira] [Commented] (HDDS-40) Separating packaging of Ozone/HDDS from the main Hadoop

Anu Engineer commented on HDDS-40:
----------------------------------

When I run from command line,

{quote} ## Development

You can run manually the robot tests with `robot` cli. (See robotframework docs to install
it.)

 1. Go to the `src/test/robotframework`
 2. Execute `robot -v basedir:${PWD}/../../.. -v VERSION:3.2.0-SNAPSHOT .`

I seem to get this following failure.
{quote}
Robotframework.Acceptance.Ozone :: Smoke test to start cluster wit... | FAIL |
Suite setup failed:
Variable '${hadoopversion}' not found.

Also suite teardown failed:
Several failures occurred:

1) Variable '${hadoopversion}' not found.

2) Variable '${hddsversion}' not found.

7 critical tests, 0 passed, 7 failed
7 tests total, 0 passed, 7 failed

Do I need to specify the HDDS version now?

> 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)
