I have used riak in a production app. Just recently switched to redis.

Riak was great for the most part. There were three nodes running on three different machines. Setting up a new node is a breeze. Eventually there become a data inconsitancy between the nodes that couldn't get resolved, and would happen intermittently.

When this happened, any sort of map reduce operation would fall. Individual keys could be requested, but only from a node that had the item.

In addition, removing a node in this inconsitant state was a no go. The other nodes would stay in the inconsitant state for good.

Interestingly enough, this only happened on certain buckets. There was a logger bucket that had keys updating and being created all the time that never had an issue.

Perhaps it was a bad configuration on our end...

I assume the cluster is no longer running? I'm curious whether your inconsistent looking bucket had allow_mult set to true?

No, allow_mult was set to false. Similarly to the author, it was running on AWS, so that may be a factor.
