The biggest user-facing changes are the YARN CLI experience. While this FLIP needs not necessarily change the parameters of the CLI, it will change the responses. For example, jobs will be accepted without first waiting for all TaskManagers to be allocated and available. The tubular housing sits at 178mm high and roughly 70mm in diameter, making it easy to slip into a bag for a day out. Weighing just 550g and featuring a convenient carry strap, it’s also light enough to lug around by hand. As well as feeling solid and durable, the overall look is suitably stylish regardless of which colour option you plump for. JmLeaderID - Unique ID of a JobManager, a fencing token like the current LeaderSessionID . Changes each time a new JobManager takes a job over. Disambiguates between messages sent by different JobManagers over time, to prevent that old stale JobManagers (who still think they are in charge) send interfering messages. Future versions of the dispatcher should receive only HTTP calls and thus can act as a bridge in firewalled clusters

Don’t let that put you off too much. Both speakers sound rich and lush, with a pleasingly easy-going soundstage that’ll suit casual listeners down to a tee - and, both come with support for JBL’s PartyBoost feature. Otherwise, both speakers offer very similar audio performances, the same level of ruggedness, and near-identical designs. By default, there is no mechanism to restart failed processes. This has to be solved by external tools, or by the availability of sufficient standby machines (TaskManagers and Dispatchers). Pending slot allocations: Lost, JobManager re-requests slots for all outstanding requests upon pending Compared to the state in Flink 1.1, the new Flink-on-YARN architecture offers the following benefits:

The JBL Flip 6 is rugged and powerful enough to be your go-to outdoor speaker but falls just short of being the best on the market

ResourceManager and JobManager run inside the master process. Failure detection and restart of that process is done by container orchestrator (Kubernetes). If a lightweight and small design is most important to you, the Flip 6 is your best bet - and that’s true if you’re also looking for the cheaper option of the two speakers. AllocationID - Slot allocation identifier, created by the JobManager when requesting a slot, constant across re-tries. Used to identify responses by the ResourceManager and to identify deployment calls towards the TaskManager that was allocated from.

With each heartbeat, the TaskManager also transmits its slot availability. That way, the ResourceManager will always know about available slots. In addition, direct notifications about slots becoming available updates the ResourceManager’s view faster. The ResourceManager no longer has a resource pool size, but receives individual requests for slots . That way, jobs can request TaskManagers of different resources (Memory/CPU). The dispatcher never executes code and can thus be viewed as a trusted process. It can run with higher privileges (superuser credentials) and spawn jobs on behalf of other users (acquiring their authentication tokens). Building on that, the dispatcher can manage user authentications

The TaskManager’s view about which slot is taken (and by which JobManager) is the ground truth - the ResourceManager derives its view from the TaskManager notifications and heartbeats. It comes in a range of colors, including white, dark blue, grey, green, camo and more. It has an IPX7 waterproof rating, which means it can be immersed in water up to a metre deep for 30 minutes.
