Elasticsearch 映射中的自定义日期格式

我正在尝试使用日期格式索引数据Tue May 14 17:06:01 PDT 2013。正如 Elasticsearch 中所述日期格式 http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-date-format.html文档我需要使用自定义日期格式。我指的是日期时间格式 http://joda-time.sourceforge.net/api-release/org/joda/time/format/DateTimeFormat.html文件和各自的格式是E M d H:m:s z Y.

我能够创建映射，但是当我尝试索引数据时，它给了我错误。

映射：-

{
  "tweet": {
    "properties": {
      "user": {
        "type": "string",
        "index": "not_analyzed"
      },
      "message": {
        "type": "string",
        "null_value": "na"
      },
      "postDate": {
        "type": "date",
        "format": "E M d H:m:s z Y"
      },
      "priority": {
        "type": "integer"
      },
      "rank": {
        "type": "float"
      }
    }
  }
}

索引文件：-

curl -XPUT 'http://localhost:9200/tweets/tweet/1' -d '{
        "user" : "kimchy",
        "message" : "This is a tweet!",
        "postDate" : "Tue May 14 17:06:01 PDT 2013",
        "priority" : 4,
        "rank" : 12.3
}'

Error:-

{"error":"MapperParsingException[failed to parse [postDate]]; 
nested: MapperParsingException[failed to parse date field [Tue May 14 17:06:01 PDT 2013],
tried both date format [E M d H:m:s z Y], and timestamp number with locale []];
nested: IllegalArgumentException[Invalid format: \"Tue May 14 17:06:01 PDT 2013\"
is malformed at \"May 14 17:06:01 PDT 2013\"]; ","status":400}

有什么建议吗？

对于月份，使用三个“M”。引用自API docs http://joda-time.sourceforge.net/api-release/org/joda/time/format/DateTimeFormat.html:

月份：3 或以上，使用文本，否则使用数字。

因此，您提供的输入的正确映射应该是：

    "postDate": {
      "type": "date",
      "format": "E MMM d H:m:s z Y"
    }
