How to modify _source parameters in Elasticsearch mapping? -

-

i'm new elasticsearch (elk) , i'm working on project done external company, won't support i'm trying making changes myself.

what i'm trying changing field name, since data coming elasticsearch has changed bit.

if run this:

curl 'http://localhost:9200/_search?pretty'

i mappings (i guess word). looks (simplified bit):

{     "_index" : ".kibana",     "_type" : "visualization",     "_id" : "count-by-clusters",     "_score" : 1.0,     "_source":{         "title":"count clusters",         "visstate":"{             "type": "histogram",             "params": {},             "aggs": [                 {                     "id": "1",                     "type": "terms",                     "schema": "group",                     "params": {                           "field": "cluster.id",                           "size": 5,                           "order": "desc",                           "orderby": "1"                     }                   },                 {                     ...                 }                ]         }     } }, {     "_index" : ".kibana",     "_type" : "visualization",     "_id" : "users-by-clusters",     "_score" : 1.0,     "_source":{         "title":"users clusters",         "visstate":"{             "type": "histogram",             "params": {},             "aggs": [                 {                     "id": "1",                     "type": "terms",                     "schema": "group",                     "params": {                           "field": "cluster.id",                           "size": 5,                           "order": "desc",                           "orderby": "1"                     }                   },                 {                     ...                 }               ]         }     } }

there 8 of these mappings, showed 2 of them.

the problem is, "field": "cluster.id" has "field": "cluster_id" , can't seem find way change that.

i tried create new mappings, error message saying .kibana exists, though have not one, 8 of these mappings "_index" : ".kibana".

i've searched documentation i'm still stuck. maybe i'm looking wrong places. appreciate and/or pointers how this.

thanks.

the error getting because .kibana default index. can re-try first deleting .kibana index using following command:-

curl -xdelete localhost:9200/.kibana

where localhost elasticsearch server address followed port.

after deleting try create mappings have been trying.
