--------------------------------------------
Summary: Split the maven modules into several profiles
Key: HADOOP-14453
URL: https://issues.apache.org/jira/browse/HADOOP-14453
Project: Hadoop Common
Issue Type: Improvement
Components: build
Reporter: Tsz Wo Nicholas Sze
Assignee: Tsz Wo Nicholas Sze
Current all the modules are defined at directly under <project>. As a result,
we cannot select to build only some of the modules. We have to build all the
modules in any cases and, unfortunately, it takes a long time.
We propose split all the modules into multiple profiles so that we could build
some of the modules by disabling some of the profiles. All the profiles are
enabled by default so that all the modules will be built by default.
For example, when we are making change in common. We could build and run tests
under common by disabling hdfs, yarn, mapreduce, etc. modules. This will
reduce the development time spend on compiling unrelated modules.
Note that this is for local maven builds. We are not proposing to change
Jenkins builds, which always build all the modules.
