   @wuzhjian 
   Under `yarn cluster` deploy mode, you can
   - set `-yD state.backend=filesystem -yD state.checkpoints.dir=hdfs://namenode:9000/flink/checkpoints -yD state.savepoints.dir=hdfs://namenode:9000/flink/savepoints` in `other parameters` (其它参数) to configure state options
   - trigger a savepoint manually by `flink savepoint <jobId> [savepointDirectory] -yid <yarnAppId>`
   - set `-s <savepointPath> -n` in `other parameters` to restore from the specific savepoint path
   
   In other deploy mode such as `local` and `session`, you can only set `state.backend`, `state.checkpoints.dir` and `state.savepoints.dir` in the configuration file `flink-conf.yaml`.
