Pradeep Ambati commented on HDFS-13822:
---------------------------------------
Uploaded an initial patch. To solve the test file dependencies, I have added
dependencies in the CMakeLists.txt (of tests folder) which will then resolve
the dependencies in the Makefile generated during the build process. To
parallelize the builds, I have used the build-helper:cpu-count to retrieve the
number of CPUs and used this as default number of build threads.
In the HDFS-13362 comments, [~jlowe] suggested that we can use maven-cmake
plugin to parallelize the build automatically. This approach automatically
computes/retrieves the number of build threads obviates the need to use
build-helper:cpu-count. I have tried that approach and got the native build
running (parallel builds) but ctest for unit tests didn't work. Is there a way
for making ctest for unit tests work with maven-cmake plugin?

> libhdfs++ has significantly increased clean build times for the native client
> on trunk. Problem is that libhdfs++ isn't build in parallel. When I tried to
> force a parallel build by specifying -Dnative_make_args=-j4, the build fails
> due to dependencies.
