---------------------------------------

             Summary: Regression in supported filesystems for RocksDB
                 Key: FLINK-9739
                 URL: https://issues.apache.org/jira/browse/FLINK-9739
             Project: Flink
          Issue Type: Bug
          Components: FileSystem, State Backends, Checkpointing
    Affects Versions: 1.5.0, 1.6.0
            Reporter: Chesnay Schepler


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.
It introduced an {{File#isAbsolute}} check, which for inaccessible files returns false.
