[jira] [Commented] (HDFS-8508) TestJournalNode fails occasionally with bind exception

    [ https://issues.apache.org/jira/browse/HDFS-8508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15255586#comment-15255586 ]

---------------------------------------

Hi.

I have created a patch for this.

The other tests in org.apache.hadoop.hdfs.qjournal.server do not have the same issues because they seem to have already used random port number.

> 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.
