elasticsearch mapping问题解决

1.报错信息如下：

[--16T00::,][WARN ][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>, :action=>["index", {:_id=>nil, :_index=>"filebeat-api-2018.07.15", :_type=>"doc", :_routing=>nil}, #<LogStash::Event:0x38a5460c>], :response=>{"index"=>{"_index"=>"filebeat-api-2018.07.15", "_type"=>"doc", "_id"=>"erO0nmQB3VHsYd1y-IbI", "status"=>, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse [params.end_day]", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"Invalid format: \"\""}}}}}

日期格式不对报错，解决办法如下，建立一个map,关掉日期格式检测，对需要日期格式的字段加上date类型字段。这里也实现了field限制，将默认的1000加到了3000.

报错：

"reason"=>"object mapping for [params.commoditys] tried to parse field [commoditys] as object, but found a concrete value"}}}}

这个ignore_malformed设置为true解决

curl -XPUT "10.66.178.20:9200/_template/template_api" -H 'Content-Type: application/json' -d'{
