[jira] [Updated] (FLINK-9739) Regression in supported filesystems
for RocksDB
[ https://issues.apache.org/jira/browse/FLINK-9739?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chesnay Schepler updated FLINK-9739:
------------------------------------
Description:
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.
