---------------------------------
Summary: Implement CheckpointRecoveryFactory based on Kubernetes
API
Key: FLINK-19544
URL: https://issues.apache.org/jira/browse/FLINK-19544
Project: Flink
Issue Type: Sub-task
Components: Deployment / Kubernetes, Runtime / Checkpointing
Reporter: Yang Wang
Fix For: 1.12.0
* *_CheckpointRecoveryFactory_*
* Stores meta information to Zookeeper/ConfigMap for checkpoint recovery.
* Stores the latest checkpoint counter.
Each component(Dispatcher, ResourceManager, JobManager, RestEndpoint) will have
a dedicated ConfigMap. All the HA information relevant for a specific component
will be stored in a single ConfigMap. The JobManager's ConfigMap would then
contain the current leader, the pointers to the checkpoints and the checkpoint
ID counter. Since “Get(check the leader)-and-Update(write back to the
ConfigMap)” is a transactional operation, we will completely solved the
concurrent modification issues and not using the "lock-and-release" in
Zookeeper.
