Hi guys,

I am trying to update the dynamic mapping to "strict" on an existing index.

To do so I tried to run the following query:

PUT /dev-jira-fetcher/\_mappings  
{  
"dynamic": "strict"  
}

I also tried this one:

PUT /dev-jira-fetcher/\_mappings  
{  
"index": {  
"mapper": {  
"dynamic": "false"  
}  
}  
}

However ES is throwing the following error:

{  
"error" : {  
"root\_cause" : [  
{  
"type" : "illegal\_argument\_exception",  
"reason" : "Setting index.mapper.dynamic was removed after version 6.0.0"  
}  
],  
"type" : "illegal\_argument\_exception",  
"reason" : "Setting index.mapper.dynamic was removed after version 6.0.0"  
},  
"status" : 400  
}

I followed this manual:  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic.html)

Thanks for your help!
