I would suggest to fix this the following way:
- There is an upcoming patch that makes the Flink codebase use the
`HighAvailabilityServices` properly in all places.
- We introduce a new HA mode called `yarnsimple` or so (next to `none`
and `zookeeper`) and instantiate a new implementation of
`HighAvailabilityServices` which is ZooKeeper independent.
- The new implementation of the High Availability Services does not use
ZooKeeper. It uses a leader service that always grants the JobManager
leadership, but also implements a way for TaskManagers to find the JobManager
(to be seen how, possibly a file in HDFS or so). It also implements a ZooKeeper
independent CompletedCheckpointStore that finds checkpoints by maintaining a
file with completed checkpoints.
That is all not a "proper" HA setup - it only works as long as there is
strictly only one master
But it comes close and is ZooKeeper independent.
Is that what you are looking for?
