---------------------------------
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 x86_64)
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.
