-----------------------------------
Summary: Include flink-ml-api and flink-ml-lib in opt
Key: FLINK-15847
URL: https://issues.apache.org/jira/browse/FLINK-15847
Project: Flink
Issue Type: Improvement
Components: Library / Machine Learning
Reporter: Hequn Cheng
Assignee: Hequn Cheng
[FLIP-39|https://cwiki.apache.org/confluence/display/FLINK/FLIP-39+Flink+ML+pipeline+and+ML+libs]
rebuilds Flink ML pipeline on top of TableAPI which moves Flink ML a step
further. Base on it, users can develop their ML jobs and more and more machine
learning platforms are providing ML services.
However, the problem now is the jars of flink-ml-api and flink-ml-lib are only
exist on maven repo. Whenever users want to submit ML jobs, they can only
depend on the ml modules and package a fat jar. This would be inconvenient
especially for the machine learning platforms on which nearly all jobs depend
on Flink ML modules and have to package a fat jar.
Given this, it would be better to include jars of flink-ml-api and flink-ml-lib
in the `opt` folder, so that users can directly use the jars with the binary
release. For example, users can move the jars into the `lib` folder or use -j
to upload the jars.
Putting the jars in the `opt` folder instead of the `lib` folder is because
currently, the ml jars are still optional for the Flink project by default.
