Comparing the state backend configurations between Flink 1.4 and 1.5, I have a question:
In Flink 1.5, we have a *state.checkpoints.dir* location and a *state.backend.rocksdb.localdir*. It was the same in Flink 1.4. However, in the case of filesystem backends, we have *state.backend.fs.checkpointdir* in Flink 1.4, but not in Flink 1.5. What has changed here? Also what is *taskmanager.state.local.root-dirs *? I don't see any description on the docs page ( https://ci.apache.org/projects/flink/flink-docs-release-1.5/ops/config.html#taskmanager-state-local-root-dirs ) Regards, James
