Haohui Mai commented on HDFS-8381:
----------------------------------
Taking a quick look of Jenkins build, some of the tests takes long time and
might be worth some investigation:

That contributes around 5% of the running time of the jenkins build.

> Components: test
> Reporter: Arpit Agarwal
>
> HDFS unit tests take a long time to run. Our unit tests are more like
> system/integration tests since we spin up a MiniDFSCluster for individual
> test cases. A number of tests have sleeps which further adds to the run time.
> A better option is to use more fine-grained unit tests specific to individual
> classes. I did not find any existing Jiras for this so filing one to track
> this work.
