Option to disable FS/URL repository based snapshots

[malpani]

I want to disable FS and URL snapshots in Elasticsearch 2.x. Essentially I do not want users of the cluster messing around with the filesystem. Users are allowed to configure S3 repositories only. Is there a way to do this today?

In general, it will be much more useful and powerful if plugins in 2.x are also allowed to override default modules as used to be the case in 1.x

I achieved this in 1.x by having a plugin do the following

repositoriesModule.registerRepository(FsRepository.TYPE, AbstractModule.class)

But 2.x seems to disallow registering same module twice and similar code throws the following error

Filing this feature request based on my question at https://discuss.elastic.co/t/how-to-disable-filesystem-url-snapshots-in-2-x/44776

You can achieve the desired behavior now by not specifying the path.repo and repositories.url.allowed_urls settings.

Exactly what @muralikpbhat said. Closing
