Hi,
I have to -1 for this rc because I found issues[1][2][3] when testing rc1,
and I think it's necessary to merge the improvements before we release.
[1] https://github.com/apache/incubator-celeborn/pull/1720
[2] https://github.com/apache/incubator-celeborn/pull/1722
[3] https://github.com/apach
+1 (non-binding)
I checked the following things:
- signatures are good.
```
gpg --import KEYS
gpg --verify apache-celeborn-0.3.0-incubating-source.tgz.asc
gpg --verify apache-celeborn-0.3.0-incubating-bin.tgz.asc
```
- checksums are good.
```
sha512sum --check apache-celeborn-0.3.0-incubating-sou
