Subject Re: Text Classification Engine Tutorial
Date Wed, 27 Sep 2017 18:30:09 GMT
Sorry for dropping the ball. Mind trying out version 5 of the template? It
looks like Lucene 6 in the latest version of the template may not be
working properly with Elasticsearch 1.x. Alternatively you can also try
using Elasticsearch 5.x with PIO instead.
