Elasticsearch: No handler for type [keyword] declared on field [hostname]

Question

I get above Mapper Parsing Error on Elasticsearch when indexing log from filebeat.

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

I have followed their own documentations, I installed filebeat template as per instructed and verified from Loading the Index Template in Elasticsearch | Filebeat Reference

My elasticsearch is normally working fine with my other data indexing and I tested them on Kibana. Its an official docker Docker Hub | Elasticsearch installation.

Googled a lot without any luck so, any help is appreciated.

UPDATE 1:

ES version: 2.3.3 (I believe latest one)

Template file is the default shipped with filebeat.

{
  "mappings": {
    "_default_": {
      "_all": {
        "norms": false
      },
      "dynamic_templates": [
        {
          "fields": {
            "mapping": {
              "ignore_above": 1024,
              "type": "keyword"
            },
            "match_mapping_type": "string",
            "path_match": "fields.*"
          }
        }
      ],
      "properties": {
        "@timestamp": {
          "type": "date"
        },
        "beat": {
          "properties": {
            "hostname": {
              "ignore_above": 1024,
              "type": "keyword"
            },
            "name": {
              "ignore_above": 1024,
              "type": "keyword"
            }
          }
        },
        "input_type": {
          "ignore_above": 1024,
          "type": "keyword"
        },
        "message": {
          "norms": false,
          "type": "text"
        },
        "offset": {
          "type": "long"
        },
        "source": {
          "ignore_above": 1024,
          "type": "keyword"
        },
        "type": {
          "ignore_above": 1024,
          "type": "keyword"
        }
      }
    }
  },
  "order": 0,
  "settings": {
    "index.refresh_interval": "5s"
  },
  "template": "filebeat-*"
}

UPDATE 2: You are right, see

#/usr/share/filebeat/bin/filebeat --version filebeat version 5.0.0-alpha2 (amd64), libbeat 5.0.0-alpha2

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

sub1.example.com:443 1.9.202.41 - - [03/Jun/2016:06:58:17 +0000] "GET /notifications/pendingCount HTTP/1.1" 200 591 0 32165 "https://sub1.example.com/path/index?var=871190" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36"

"message" => "%{HOSTNAME:vhost}\:%{NUMBER:port} %{COMBINEDAPACHELOG}"

Answer 1

You cannot use "type": "keyword" with ES 2.3.3 since that's a new data type in ES 5 (currently in alpha3)

You need to replace all those occurrences with

"type": "string",
"index": "not_analyzed"

You need to use filebeat.template-es2x.json instead.
