StephanEwen commented on issue #6452: [FLINK-9739] Regression in supported
filesystems for RocksDB
URL: https://github.com/apache/flink/pull/6452#issuecomment-412559130
Do we want to restore the previous behavior? I mean, RocksDB paths must be
local file paths. Having URIs with file system schemes in there seems like a
mistake of the past. That is also the reason why splitting at `:` causes
trouble, because URIs and directory lists don't go together well.
We could simply drop the old behavior and help smoothen the transition.
- Drop the check for absolute path and allow relative paths
- If "file" occurs as a segment in the path list, abort with the proper
exception that mentions that URIs are not supported any more and the user
should switch to file paths only.

> has reported that the {{RocksDBStateBackend}} no longer supports GlusterFS
> mounted volumes.
> Configuring {{file:///home/abc/share}} lead to an exception that claimed the
> path to not be absolute.
> This was working fine in 1.4.2.
> In FLINK-6557 the {{RocksDBStateBackend}} was refactored to use java
> {{Files}} instead of Flink {{Paths}}, potentially causing the issue.
