Subject CheckpointConfig says to persist periodic checkpoints, but no checkpoint directory has been configured.
Date Tue, 26 Sep 2017 03:49:36 GMT
Hi I am running flink in dev mode through Intellij, I have flink-conf.yaml
correctly configured and from the log you can see job manager is reading it.

*But I still somehow get this error*
java.lang.IllegalStateException: CheckpointConfig says to persist periodic
checkpoints, but no checkpoint directory has been configured. You can
configure configure one via key 'state.checkpoints.dir'.

*My program only has this related to checkpointing*

val env = StreamExecutionEnvironment.*getExecutionEnvironment
*env.getCheckpointConfig.enableExternalizedCheckpoints(ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION)env.enableCheckpointing(2
* 60 * 1000)


Need some help to dig through this. Thanks
