[jira] [Commented] (FLINK-15491) Fix incorrect path while missing trailing slash of high-availability.zookeeper.path.running-registry parameter.

["Yun Tang (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-15491?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17009034#comment-17009034 ] 

Yun Tang commented on FLINK-15491:
----------------------------------

This is because the zk path is only created by append two string [together|https://github.com/apache/flink/blob/229d02147ee4d57deb05c28a5626f44aca7fcba5/flink-runtime/src/main/java/org/apache/flink/runtime/highavailability/zookeeper/ZooKeeperRunningJobsRegistry.java#L121].

{code:java}
	private String createZkPath(JobID jobID) {
		return runningJobPath + jobID.toString();
	}
{code}

But from what I can see, even we forget to add a slash in the end, that would not cause any real harmful result but only a strange path.

> By default, the value of configuration *high-availability.zookeeper.path.running-registry* must end with a slash. If we set this parameter as following:
> {code:java}
> high-availability.zookeeper.path.running-registry: /running_job_registry{code}
> an incorrect path will be created, as shown in the following picture
