Hi @tillrohrmann I added a unit test
`FsCheckpointStorageTest#testResolveCheckpointStorageLocation()` to guard the
changes. But I still use one `mock` for creating two different file systems(one
for checkpoint, another for savepoint), because without mock I can only create
a LocalFileSystem in the test. Could you please have a look again?
> Flink doesn't use the Savepoint path's filesystem to create the OuptutStream

> Currently, flink use the Savepoint's filesystem to create the meta output
> stream in CheckpointCoordinator(JM side), but in StreamTask(TM side) it uses
> the Checkpoint's filesystem to create the checkpoint data output stream. When
> the Savepoint & Checkpoint in different filesystem this will lead to
> problematic.
