Elasticsearch: No handler for type [keyword] declared on field [hostname]
<p>I get above Mapper Parsing Error on Elasticsearch when indexing log from filebeat.</p>

<p>I tried both Filebeat -> Elasticserach and Filebeat -> Logstash -> Elasticsearch approach.</p>

<p>I have followed their own documentations, I installed filebeat template as per instructed and verified from <a href="https://www.elastic.co/guide/en/beats/filebeat/1.2/filebeat-template.html" rel="noreferrer">Loading the Index Template in Elasticsearch | Filebeat Reference</a></p>

<p>My elasticsearch is normally working fine with my other data indexing and I tested them on Kibana. Its an official docker <a href="https://hub.docker.com/_/elasticsearch/" rel="noreferrer">Docker Hub | Elasticsearch</a> installation.</p>

<p>Googled a lot without any luck so, any help is appreciated.</p>

<p><strong>UPDATE 1:</strong></p>

<p>ES version: 2.3.3 (I believe latest one)</p>

<p>Template file is the default shipped with filebeat.</p>

<p><strong>UPDATE 2:</strong>
You are right, see</p>

<p><code>#/usr/share/filebeat/bin/filebeat --version
filebeat version 5.0.0-alpha2 (amd64), libbeat 5.0.0-alpha2</code></p>

<p>Though this is posting apache log to logstash. But I can't get this vhost_combined log in right format</p>
