Steve Loughran commented on HADOOP-8545:
----------------------------------------
I'm looking at this. One thing I don't understand is the logic in
{{SwiftNativeFileSystem.create()}}, after getting the file status:
{code}
if (fileStatus != null && !fileStatus.isDir()) {
if (overwrite) {
delete(file, true);
} else {
throw new IOException("File already exists: " + file);
}
} else {
Path parent = file.getParent();
if (parent != null) {
if (!mkdirs(parent)) {
throw new IOException("Mkdirs failed to create " + parent.toString());
}
}
}
{code}
I can see that the "don't overwrite an existing file unless
{{overwrite==true}}" is there, but what does it mean if the path exists and is
a directory? That it's just a no-op?
If so I'd like to change the logic to make it more explicit what is going on.
