lindong28 opened a new pull request #1:
URL:
https://github.com/apache/flink-ml/pull/1 ## What is the purpose of the change
Move Flink ML pipeline API and library code from apache/flink to apache/flink-ml
## Brief change log
- Move files under flink/flink-ml-parent to flink-ml repo
- Add CODE_OF_CONDUCT.md, LICENSE and .gitignore
- Add files needed for checkstyle under tools/maven
- Update pom.xml to include plugins from apache/flink/pom.xml that are needed to build and release this flink-ml repo.
## Verifying this change
1) This PR could run and pass all unit tests.
2) Run `mvn install` in both `apache/flink-ml` and `apache/flink/flink-ml-parent` and verify that they generate the same set of files (e.g. *.pom files and *.jar files) at the same path under `~/.m2/repository/org/apache/flink/`
3) `mvn install` generates `flink-ml-api-1.13-SNAPSHOT.jar`, `flink-ml-lib_2.11-1.13-SNAPSHOT.jar` and `flink-ml-uber_2.11-1.13-SNAPSHOT.jar`. I used IntellIj to compare the jar files with those jar files generated by `apache/flink/flink-ml-parent` and verified that they contains the same class files.
The only difference in the jar files is that the jar file from this repo has NOTICE that says "Copyright 2019-2020 The Apache Software Foundation", whereas the jar file from apache/flink has NOTICE that says "Copyright 2014-2021 The Apache Software Foundation". That is not clear to me where that difference comes from. I believe this is not a blocking issue.
