Ah, I'm planning to revert this commit
https://github.com/apache/incubator-hivemall/commit/1e940aff316b1a91484ad08ba286492892b32d07
of v0.5.0 branch for rc2 release.
```
git checkout v0.5.0
git reset --hard HEAD^
```
0.5.1-SNAPSHOT is for next development iteration. No need to do it in
v0.5.0 branch; however, Maven release plugin sets the development version.---
