How to run hdfs unit tests ?

[xiaohe lan]

Hello,

I am new to hdfs, I want to know how to run a specific unit test of hdfs. I
have imported hdfs project into IntelliJ IDEA, I can run a test just by
right-click on the test and select Run test. Can I run a unit test from
terminal and how ? I want to learn some hdfs APIs so I may add some code to
the unit tests code and some a test.

Thanks,
Xiaohe
