-----------------------------------
Summary: Clean up FileSystem
Key: FLINK-5812
URL: https://issues.apache.org/jira/browse/FLINK-5812
Project: Flink
Issue Type: Improvement
Components: Core
Affects Versions: 1.2.0
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Priority: Minor
Fix For: 1.3.0
The {{FileSystem}} class is overloaded and has methods that are not well
supported. I suggest to do the following cleanups:
- Pull the safety net into a separate class
- Use the {{WriteMode}} to indicate overwriting behavior. Right now, the
{{FileSystem}} class defines that enum and never uses it. It feels weird.
- Remove the {{create(path, overwrite, blocksize, reolication, ...)}} method,
which is not really supported across file system implementations. For HDFS,
behavior should be set via the configuration anyways.
All changes have to be made in a non-API-breaking fashion.
