Chesnay Schepler commented on FLINK-9739:
-----------------------------------------

New info, according to the user it even fails for local file-systems:
{code}
state.backend: rocksdb
state.checkpoints.dir: file:///home/demo/checkpoints/ext_checkpoints
state.savepoints.dir: file:///home/demo/checkpoints/checkpoints/savepoints
state.backend.fs.checkpointdir: file:///home/demo/checkpoints/checkpoints/fs_state
#state.backend.rocksdb.checkpointdir: file:///home/demo/checkpoints/checkpoints/rocksdb_state
state.backend.rocksdb.localdir: /home/demo/checkpoints/checkpoints/rocksdb_state
{code}

>             Project: Flink
>          Issue Type: Bug
>          Components: FileSystem, State Backends, Checkpointing

> A user reporter on the [mailing list|http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Checkpointing-in-Flink-1-5-0-tt21173.html]
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.
