Hi, The issue seems to be connected with trying to restart the job in the detached mode. The stack trace is as follows:

I have an HA cluster running with 1 Master and 4 Workers. The flink-config.yaml is as follows : #============================================================================== # Common #============================================================================== jobmanager.rpc.address: stable-stream-master01.app.shared.int.sv2.247-inc.net # The port where the JobManager's main actor system listens for messages. jobmanager.rpc.port: 6123 # The heap size for the JobManager JVM jobmanager.heap.mb: 512 # The heap size for the TaskManager JVM taskmanager.heap.mb: 2048 # The number of task slots that each TaskManager offers. Each slot runs one parallel pipeline. taskmanager.numberOfTaskSlots: 8 # Specify whether TaskManager memory should be allocated when starting up (true) or when # memory is required in the memory manager (false) taskmanager.memory.preallocate: false # The parallelism used for programs that did not specify and other parallelism. parallelism.default: 1 env.java.home: /usr/local/java restart-strategy: fixed-delay restart-strategy.fixed-delay.attempts: 2 restart-strategy.fixed-delay.delay: 10 s #============================================================================== # Web Frontend #============================================================================== # The port under which the web-based runtime monitor listens. # A value of -1 deactivates the web server. jobmanager.web.port: 8081 # Flag to specify whether job submission is enabled from the web-based # runtime monitor. Uncomment to disable. #jobmanager.web.submit.enable: false #============================================================================== # Streaming state checkpointing #============================================================================== # The backend that will be used to store operator state checkpoints if # checkpointing is enabled. # # Supported backends: jobmanager, filesystem, <class-name-of-factory> # state.backend: filesystem # Directory for storing checkpoints in a Flink-supported filesystem # Note: State backend must be accessible from the JobManager and all TaskManagers. # Use "hdfs://" for HDFS setups, "file://" for UNIX/POSIX-compliant file systems, # (or any local file system under Windows), or "S3://" for S3 file system. # state.backend.fs.checkpointdir: file:///home/amallem/ state.savepoints.dir: file:///home/amallem/save/ #============================================================================== # Master High Availability (required configuration) #============================================================================== # The list of ZooKepper quorum peers that coordinate the high-availability # setup. This must be a list of the form: # "host1:clientPort,host2[:clientPort],..." (default clientPort: 2181) # recovery.mode: zookeeper # recovery.zookeeper.quorum: stable-stream-zookeeper01.app.shared.int.net:2181,stable-stream-zookeeper02.app.shared.int.net:2181 # # Note: You need to set the state backend to 'filesystem' and the checkpoint # directory (see above) before configuring the storageDir. # recovery.zookeeper.storageDir: file:///home/amallem/recovery recovery.zookeeper.path.root: /flink recovery.zookeeper.path.namespace: /cluster_one Query : I am able to take a save point and then cancel my current job but when I try to start the job again using the save point I get the error stating “ProgramInvocationException: JobManager did not respond within 60000ms”. I checked Zookeeper and everything seems fine. I also followed the recommendations in the following post : http://stackoverflow.com/questions/36625742/cant-deploy-flow-to-ha-cluster-of-apache-flink-using-flink-cli Is there any configuration I am missing to enable restarting of the job. Any help will be appreciated. Thanks. Regards, Anirudh
