Hello, We currently have a 4-node Elasticsearch 0.15 cluster running using NIO FS with the Local gateway type. It works very well and so far we are quite happy with the platform in general (so thanks for that!). I am curious to know if there is a suggested migration path for moving from using Local FS to another gateway, such as HDFS or S3 (via Scality, for example)? Is it possible to do with minimal pain? I'd rather not lose any data, if possible. 🙂 Thank you all ! -- Daniel Maher « can't talk, too busy calculating computrons. » ---

Changing the gateway type requires reindexing of the data, there is no migration from local gateway to shared (S3 or HDFS)... . You can start another cluster and reindex the data there, and then switch between the two.
