sampathBhat commented on issue #6452: [FLINK-9739] Regression in supported
filesystems for RocksDB
URL: https://github.com/apache/flink/pull/6452#issuecomment-408839099
hi @zentol. splitting based on : was added to support multiple file paths.
In windows File.pathSepertor= ";" where as in unix its File.pathSepertor=
":".
The reference you pointed https://github.com/apache/flink/pull/2482 is
correct but in that code base the implementation of setDbStoragePaths() is
different from current code base. That is the change in API from
org.apache.flink.core.fs.Path to java.io.File and the introduction of an extra
File.isAbsolute() check.
Due to the above changes in setDbStoragePaths() its not possible to provide
the configuration like this-
state.backend.rocksdb.localdir = file:///some/file/path. If I'm not wrong
this is valid way of providing config.

> 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.
