----------------------------------------------------------
This is because the zk path is only created by appending 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
