Hi Mathieu, I'm CCing the Spark user list since this will be of general interest to the forum. Unfortunately, there is not a way to begin LDA training with an existing model currently. Some MLlib models have been augmented to support specifying an "initialModel" argument, but LDA does not have this yet. Please feel free to make a feature request JIRA for it!
