Updating settings for all indices in an Amazon Hosted Elasticsearch Cluster

Hi,

I'm trying to update a particular setting for all indices on one of our Elasticsearch clusters with a PUT request for _settings without specifying the index, which according to the documentation updates the specified settting for all indices.

That is returning a :

{"Message":"Your request: '/_settings' is not allowed."}

After researching some more apparently we can't do that on AWS hosted Elasticsearch solutions so we have to go index by index and update the settings which is a pain in the ass.

Is there any other workaround we can implement?

Can you not update /*/_settings ? If not I suspect this is something you need to bring up with Amazon support as I am not aware what possible restrictions they have implemented on their Elasticsearch version.
