> TestPipeApplication silently hangs. 
> This happens both on my machine and in the CI runs.
> This is actually two problems:
>  - The test hangs
>  - The hang does not appear in the CI output, and does not cause the test to 
> fail
> The snippet below is from 
> https://ci-hadoop.apache.org/job/hadoop-qbt-trunk-java11-linux-x86_64/827/artifact/out/patch-unit-hadoop-mapreduce-project_hadoop-mapreduce-client_hadoop-mapreduce-client-jobclient.txt/*view*/:
