> Inconsistencies in some FileSystem directory functions

> Key: FLINK-8373
> URL: https://issues.apache.org/jira/browse/FLINK-8373
> Project: Flink
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.4.0
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Priority: Minor
> Fix For: 1.5.0
>
>
> There are some minor differences in the behaviors of some File System
> functions, like {{mkdirs()}}. On some filesystems, it tolerates existing
> directories or files in place of parent directories. Some return false in an
> error case, some throw an exception.
> I encountered this during writing tests for the file basted state backends.
> We should harmonize the behavior of {{FileSystem.mkdirs()}}.
> I suggest to adopt the behavior that is used by HDFS, which seems the most
> correct one.
