I'm following some elasticsearch-py tutorial and When I try to use elasticsearch python client to create some index, I get the following error message: > > > from elasticsearch import Elasticsearch > > > es = Elasticsearch() > > > from datetime import datetime > > > doc = {'author':'kimchy','timestamp':datetime.now()} > > > res = es.index(index='test-index',doc\_type='tweet',id=1,body=doc) > > >

elasticsearch, I got the following error message in the elasticsearch powershell window: [2017-06-20T09:20:16,740][INFO][o.e.n.Node] [ZSbyQ6h] started
