Hi @jlowe , do you mean this commit id?

[jlowe]

Yes, I mean that commit. It's weird in that I can see the commit in the commits to be merged, yet when I diff this PR against branch-24.06 there are some missing changes that I thought were coming from #388. For example:

$ git fetch https://github.com/nvliyuan/spark-rapids-examples.git main-2406-release

We can see from the diff above that we're rolling back changes in branch-24.06 as part of this merge of that branch to main. Not quite sure why these changes were lost despite #388 being part of the commit list in this PR (bad merge conflict resolution maybe?), but it needs to be fixed. You can do a diff like I show above to verify all of the changes between this PR and branch-24.06 make sense.

Hi @jlowe, thanks for pointing it put, I just checked the diff details, basically there are three part:
part1: I miss some commits while doing the merge conflict, for example:

part2: There are something wrong in branch-2406, since PCA demo only compatible with spark-rapids v23.04, cuspecial demo only compatible with spark-rapids v23.02, we miss this during the previous release, for example:

For part1, I already push some commits to fix that
For part2, I already draft pr #398 to fix the version issue in branch-2406
For part3, I assume we could ignore them.
Now if you do a diff to compare main-2406-release and branch-2406, there should be only snapshot version diffs.

[jlowe]

Yes, snapshot diffs are expected. The other two need to be fixed.

Nit: Given there were a number of merge mistakes on this PR, it would be cleaner to wait for #398 to be fixed and then re-merge branch-24.06 to main in a fresh PR. We're not squashing commits for this, and all these "fix" commits will appear in the mainline release. The mainline history ideally should have a minimal number of divergent commits from the dev branches. Not must-fix for me, just would be nice.

close this pr and draft new pr #401
