Unfortunately, this breaks the API's binary compatibility. That's why the
issue is also a sub-issue of the Flink 2.0 breaking changes. I think we need to
delay this until we start the 2.0 branch.
> Make Path immutable

> Key: FLINK-5336
> URL: https://issues.apache.org/jira/browse/FLINK-5336
> Project: Flink
> Issue Type: Sub-task
> Components: Core
> Reporter: Stephan Ewen
> Assignee: Anton Solovev
> Fix For: 2.0.0
>
>
> The {{Path}} class is currently mutable to support the {{IOReadableWritable}}
> serialization. Since that serialization is not used any more, I suggest to
> drop that interface from Path and make the Path's URI final.
> Being immutable, we can store configures paths properly without the chance of
> them being mutated as side effects.
> Many parts of the code make the assumption that the Path is immutable, being
> susceptible to subtle errors.
