Errs out on empty cluster with Shield #33

Closed alexbrasetvik closed 8 years ago

alexbrasetvik commented 8 years ago

An empty cluster should be trivially updatable. However, if Shield is enabled, the _aliases-lookup will err IndexMissingException[[_all] missing] instead of returning an empty list, resulting in an error.

This is a problem with Shield: https://www.elastic.co/guide/en/shield/current/limitations.html#_changes_in_index_wildcard_behavior

I don't see how to fix this in the migration plugin.

Fortunately, if you have an empty cluster, upgrading shouldn't be too tricky :)
