[jira] [Created] (FLINK-8373) Inconsistencies in some FileSystem directory functions

Stephan Ewen created FLINK-8373:
-----------------------------------

             Summary: 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.
