-------------------------------------
[~heahmed]
The introduced test seems to be flaky. It doesn't pass for me locally ever &
there is a failure in the Jenkins job as well,
[https://ci-hadoop.apache.org/job/hadoop-multibranch/job/PR-6692/9/testReport/org.apache.hadoop.hdfs.util/TestCombinedHostsFileReader/testReadFileWithTimeoutInterruptedException/]
Can you give a check & push an Addendum PR to fix?

> Certain implementations of Hadoop have the dfs.hosts file residing on NAS/NFS
> and potentially with symlinks. If the FS hangs for any reason, the
> refreshNodes call would infinitely hang on the HostsFileReader until the FS
> returns.
