无法为通过logstash JDBC输入插件创建的索引创建elasticsearch的映射

我正在尝试mappings为elasticsearch创建index。当我使用以下查询创建索引时，可以应用mappings。

请在elasticsearch中找到创建索引的查询

put index/profile/1
{
    "firstname" : "Karthik",
    "lastname" : "AS",
    "address" : "4/167, SouthExtn, shanmuga nagar, NA",
    "Skill" : "Java, JEE, ReactJS, ActiveMQ, ElasticSearch",
    "filename" : "My_second_file_created_at_2012.01.13.pdf"
}

对于上面创建的索引，它可以应用mappings并能够成功搜索。请找到以下mappings详细信息

    PUT /documents_test8
{
   "settings" : {
      "analysis" : {
         "analyzer" : {
            "filename_search" : {
               "tokenizer" : "filename",
               "filter" : ["lowercase"]
            },
            "filename_index" : {
               "tokenizer" : "filename",
               "filter" : ["lowercase","edge_ngram"]
            }
         },
         "tokenizer" : {
            "filename" : {
               "pattern" : "[^\\p{L}\\d]+",
               "type" : "pattern"
            }
         },
         "filter" : {
            "edge_ngram" : {
               "side" : "front",
               "max_gram" : 20,
               "min_gram" : 1,
               "type" : "edgeNGram"
            }
         }
      }
   },
   "mappings" : {
      "doc" : {
         "properties" : {
            "filename" : {
               "type" : "text",
               "search_analyzer" : "filename_search",
               "index_analyzer" : "filename_index"
            }
         }
      }
   }
}

但是在实际情况下，我正在通过logstash JDBC输入插件在elasticsearch中创建索引。能够在elasticsearch中创建索引，但是一旦默认情况下通过logstash在elasticsearch中创建了索引，该问题mappings也会为该索引（对于所有字段）创建。之后，我将无法应用mappings它显示index [documents_test9/P07B6_6mRqmH9IP-UaCjrw] already exists错误。如果我尝试删除该索引并执行此mapping我得到Failed to parse mapping [doc]: No handler for type [string] declared on field [filename]的错误。

不确定，如何mappings通过logstash JDBC输入插件创建索引时如何应用
