Hi !
We are trying flink in HA mode. Our application is a streaming application with windowing mechanism. We set in the flink yaml : state.backend: filesystem recovery.mode: zookeeper recovery.zookeeper.quorum:<Our quorum> recovery.zookeeper.path.root: <path> recovery.zookeeper.storageDir: <storageDir> recovery.backend.fs.checkpointdir: <pathcheckpoint> yarn.application-attempts: 100 We want in case of application crash, the pending window has to be restore when the application restart. Pending data are store into the <storageDir>/blob directory ? Also, we try to write a script who restart the application after exceed the max attempts, with the last pending window. How can I do that ? A simple restart of the application is enough, or do I have to "clean" the recovery.zookeeper.path.root ? Thanks ! Thomas Lamirault
