https://github.com/apache/flink/pull/2550
Can we try and unify the structure / paths under which all this information
is stored in ZooKeeper?
```
/flink
+/cluster_id_1/resource_manager_lock
| |
| +/job-id-1/job_manager_lock
| | /checkpoints/latest
| | /latest-1
| | /latest-2
| |
| +/job-id-2/job_manager_lock
|
+/cluster_id_2/resource_manager_lock
|
+/job-id-1/job_manager_lock
|/checkpoints/latest
| /latest-1
|/persisted_job_graph
```
The "cluster-id" should be a generated UUID in the case of YARN/Mesos, and
should be a config value in the standalone case. In Yarn / Mesos, the UUID
should be passed via an environment variable to the Java processes with the
entry points for TaskManager / JobManager / ResourceManager.
In the Constructor, the ZooKeeper HA Services should get the "cluster-id".
