Eric Yang commented on HDDS-1521:
---------------------------------
[~elek] The current file structure is awkward and I requested to use FHS
structure initially. This issue was created by quoting me. Hence, I would
like the title to be more accurately reflect the intend. HDDS-1565 is an
example of twisting my words that k8s rename to docker becomes docker-build
without proper consent because the title was changed during the review process.
The rename of the title is my reaction to ensure that you don't put too much
extra touch in my words to incur bad faith.
If the current title works better for you, and you are willing to make the
structure change to be more FHS like, then I welcome this change. Otherwise, I
don't intend to create more work, if presentation aspect of the structure
doesn't improve.

> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Elek, Marton
> Priority: Major
>
> The conversation of the current ozone directory structure is started here:
> HDDS-1458
> By [~eyang]
> {quote}The proposal is to generate test artifacts in
> ozone-[version]/share/ozone/tests for fault injection test framework in
> release binary tarball.
> {quote}
> By [~anu]:
> {quote}Let us drop the share and make it tests/blockade, and tests/smoketests
> etc. That way, all tests that we ship can be found easily. Otherwise I am +1
> on this change.
> {quote}
> By [~elek]
> {quote}I agree with Anu. I think It's time to revisit the current structure
> of ozone distribution tar files. The original structure is inherited from
> HADOOP-6255 which is defined for a project which includes multiple subproject
> (hadoop, yarn,...) and should support the creation of different RPM package
> from the same tar. I think for ozone we can improve the usability with
> reorganizing the dirs to a better structure.
> But I am fine to do it in a separated jira and keep it in the share/test
> until that to make progress.
> {quote}
> By [~eyang]
> {quote}The reason for HADOOP-6255 was more than just RPM packaging. The
> motivation behind the reorganization was to make a directory structure that
> can work as standalone tarball as well as follow the general guideline for
> [Filesystem Hierarchy
> Standard|https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard]. This
> was proposed because a several people saw the need to make the structure more
> unix like for sharing dependencies for larger eco-system to work. This is the
> reason that Hadoop HDFS, Mapreduce have good integration between projects to
> reduce shell script bootstrap cost. Earlier version of YARN did not follow
> the conventional wisdom and it was hard to integrate with rest of Hadoop,
> YARN community struggled on classpath issue for at least 2+ years and the
> time to hype YARN framework had already passed. Given there is a high
> probability that we want to make ozone as universal as possible for
> applications to integrate with us. It given us more incentive to make the
> structure as flexible as possible. This is only a advice from my own past
> scaring. There are no perfect solution, but the conventional wisdom usually
> have endure test of time and save energy.
> {quote}
> I propose the following method:
> # Start an independent discussion, let's don't mix this question with
> HDDS-1458 and don't block it.
> # Let's propose a more use friendly directory structure first
> # Let's ask [~eyang] to defined _technical_ problems regarding to the
> proposal.
> There are two different view here:
> # Technical limitations which were mentioned earlier
> # Theoretical questions (do we need to have the same structure for core
> Hadoop and Ozone packages)
> I propose to start the discussion with the first one.
