Hello,  
I have created one index. in which I send one field name as "elapsed\_time" as float. for that, I use logstash filter for converting data types. but it is added as a string into elasticsearch instead of float. I am facing shards failed issue of this. please help me to solve this.

What does your Logstash config look like? What does the event look like once indexed into Elasticsearch?
