---------------------------------
[~StephanEwen] Here is my code. I think the checkpoint directory in
CheckpointCoordinator is still empty even if you set direcotry in
FsStateBackend.
{code:java}
val env = StreamExecutionEnvironment.getExecutionEnvironment
env.enableCheckpointing(15000)
env.getCheckpointConfig.enableExternalizedCheckpoints(ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION)
env.setStateBackend(new FsStateBackend(checkpointDir)){code}
1. If I don't set state.checkpoint.dir, it will throw exception above.
2. If i remove the third line, it will be okay.
> Enable configuration for state.checkpoint.dir in StreamExecutionEnvironment

> Reporter: buptljy
> Priority: Major
>
> Usually we can set state.checkpoint.dir in flink-conf.yaml, but sometimes we
> run a flink job locally, and we're not able to set state.checkpoint.dir for
> background wrapped cluster, which will cause
> {code:java}
> throw new IllegalStateException("CheckpointConfig says to persist periodic " +
> "checkpoints, but no checkpoint directory has been configured. You can
> " +
> "configure configure one via key '" +
> ConfigConstants.CHECKPOINTS_DIRECTORY_KEY + "'.");
> {code}
> I wonder if we could provide a public method in *StreamExecutionEnvironment*
> so that developers can use it to set state.checkpoint.dir for job.
