Tsz Wo Nicholas Sze updated HADOOP-14453:
-----------------------------------------
Attachment: c14453_20170524.patch
c14453_20170524.patch: splits the modules into 4 profiles:
- common-modules
- hdfs-modules
- yarn-modules
- other-modules
Then, we may skip building some of the modules by disabling some profiles. For
example, the following command build on common and hdfs modules.
{code}
mvn -P-yarn-modules,-other-modules test -Dtest=...
{code}
> Split the maven modules into several profiles

> 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.
