tillrohrmann commented on issue #8068: [FLINK-12042][StateBackends] Fix RocksDBStateBackend's mistaken usage of default filesystem URL: https://github.com/apache/flink/pull/8068#issuecomment-486331017 Implicitly relying on the fact that someone else has created the directory is dangerous and super brittle imo. Moreover, the code in this location does not enforce by any mean that we use the local file system. Afaik RocksDB needs a local directory for checkpointing but if this is the case, then we should explicitly enforce it (e.g. allowing only local temporary `SnapshotDirectories`).
