Flink 1.0.0 Release Candidate 0: Please help testing

[rmetzger0]

Hi,

I've now created a "preview RC" for the upcoming 1.0.0 release.

There are still some blocking issues and important pull requests to be merged but nevertheless I would like to start testing Flink for the release.

In past major releases, we needed to create many release candidates, often for fixing just some small issues. I would like to speed up the release process by collecting as many issues as possible now with the RC0. Once these issues are resolved, we can start voting with the RC1.

We have a Wiki page https://cwiki.apache.org/confluence/display/FLINK/Releasing containing some common release verification tasks.

Also, production users are encouraged to participate in the release verification process.

Here are the preview binaries located: http://people.apache.org/~rmetzger/flink-1.0.0-rc0/

This is the staging repository: https://repository.apache.org/content/repositories/orgapacheflink-1062

To use the release candidate in an existing pom project, set the Flink version to 1.0.0 and the repository URL to https://repository.apache.org/content/repositories/orgapacheflink-1062.

The pom should look like this:

<properties>
   <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   <flink.version>1.0.0</flink.version>
</properties>

<repositories>
   <repository>
      <id>flink.release-staging</id>
      <name>Apache Development Snapshot Repository</name>
      <url>https://repository.apache.org/content/repositories/orgapacheflink-1062</url>
      <releases><enabled>true</enabled></releases>
      <snapshots><enabled>false</enabled></snapshots>
   </repository>
</repositories>

Let me start a list of issues we need to resolve:

- Ensure the release is build with maven < 3.3 (the RC0 has been build with Maven 3.3, so the Guava shading is not done properly.)

- flink-cep depends on Scala, but the artifact doesn't have a scala version suffix.

- the flink-quickstart-java is referring to scala 2.11 by default.

Please add more issues to the list ....

Found one blocker issue during testing:

  - Watermark generators accept negative watermarks (FLINK-3415)
