Edmond created FLINK-11132:
------------------------------

             Summary: Restore From Savepoint on HA Setup
                 Key: FLINK-11132
                 URL: https://issues.apache.org/jira/browse/FLINK-11132
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.7.0, 1.6.2
         Environment: flink-conf.yaml:

high-availability: zookeeper
high-availability.zookeeper.quorum: zookeeper-host:2181
high-availability.zookeeper.path.root: /flink
high-availability.cluster-id: our_cluster_id
high-availability.storageDir: gs://app_bucket/flink_ns/ha
high-availability.jobmanager.port: 6123
state.backend.fs.memory-threshold: 0
state.checkpoints.dir: gs://app_bucket/flink_ns/checkpoints
state.savepoints.dir: gs://app_bucket/flink_ns/savepoints

When we tried to run it in non-HA mode we just removed the high-availability.* parameters.

Job Manager command before restore:

./standalone-job.sh start-foreground --job-classname  com.TestApp -Djobmanager.rpc.address=127.0.0.1 -Dparallelism.default=1 -Dblob.server.port=6124 -Dquery.server.ports=6125

Job Manager command when trying to restore:

./standalone-job.sh start-foreground --job-classname  com.TestApp -Djobmanager.rpc.address=127.0.0.1 -Dparallelism.default=1 -Dblob.server.port=6124 -Dquery.server.ports=6125 --fromSavepoint gs://app_bucket/flink_ns/savepoints/savepoint_1/savepoint-000000-e7f1f0f63c41

 

Task Manager command:

./taskmanager.sh start-foreground -Djobmanager.rpc.address=127.0.0.1

 
            Reporter: Edmond


In our current setup we have one job-manager (standalone-job.sh) and one task-manager (taskmanager.sh) deployed as job-cluster in HA mode (ZooKeeper).

We tried to run a simple stateful Flink app that generates periodically checkpoints and savepoints to a shared storage, in order to re-run it again from a specific savepoint later. However, when in HA it a seems that it ignores the savepoint restore flag (--fromSavepoint) and recover from the last checkpoint instead. When we removed the HA configuration, savepoint restoration was successful.
