Anu Engineer commented on HDDS-276:

[~aw] Thanks for the feedback. You bring in a valuable perspective, we are so deep in development
that we subconsciously tend to optimize for our own experience than users. I really appreciate
the point of view that you bring. We will fix this the way you are suggesting, that is fix
this in a portable manner in HDDS-280. Thanks for taking time to comment and share your perspective.

>            Priority: Minor

>         Attachments: HDDS-276.001.patch
> Ozone is creating a symlink during the dist process.
> Using the "ozone" directory as a destination name all the docker-based acceptance tests
and docker-compose files are more simple as they don't need to have the version information
in the path.
> But to keep the version specific folder name in the tar file we create a symbolic link
during the tar creation. With the symbolic link and the '–dereference' tar argument we can
create the tar file which includes a versioned directory (ozone-0.2.1) but we can use the
a dist directory without the version in the name (hadoop-dist/target/ozone).
> Currently this symlink creation has an issue. It couldn't be run twice. You need to do
a 'mvn clean' before you can create a new dist.
> But fortunately this could be fixed easily by checking if the destination symlink exists.
