> TestJournalNode fails occasionally with bind exception
> ------------------------------------------------------
>
> Key: HDFS-8508
> URL: https://issues.apache.org/jira/browse/HDFS-8508
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 2.7.0
> Reporter: Arpit Agarwal
>
> TestJournalNode uses the default port for {{dfs.journalnode.http-address}} so
> it fails occasionally when running with {{-Pparallel-tests}}.
> The same issue likely exists with other tests. Tests should generate a random
> port number with retry to reduce the chances of a collision.
