Arpit Agarwal created HDFS-8508:
-----------------------------------
Summary: 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.
