Subject [jira] [Created] (FLINK-7229) Flink doesn't deleted old checkpoint
Date Wed, 19 Jul 2017 13:07:00 GMT
Jason Zhou created FLINK-7229:

             Summary: Flink doesn't deleted old checkpoint
                 Key: FLINK-7229
                 URL: https://issues.apache.org/jira/browse/FLINK-7229
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.3.1
         Environment: Six Flink nodes running on Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-121-generic
            Reporter: Jason Zhou

I have a 6-node Flink cluster where one contains jobmanager and the others have only taskmanagers.
All taskmanagers have the following config :
state.backend: rocksdb
state.backend.rocksdb.checkpointdir: file:///opt/flink/data/local-checkpoints
state.backend.fs.checkpointdir: file:///opt/flink/data/local-checkpoints
state.checkpoints.dir: file:///opt/flink/data/glusterfs/external-checkpoints
state.checkpoints.num-retained: 3
And both checkpoints and external-checkpoints are enabled in my code.  I can see that for
the external-checkpoint, Flink retains 3 checkpoints metadata. However, for the local-checkpoint,
only one node(with jobmanager) retains 3 checkpoints and the others don't delete checkpoints.
