Tile map - Kibana

Hi All,
I am having tile map issues in my kibana 4.6 (The "logstash_netflow_cisco*" index pattern does not contain any of the following field types: geo_point¬ ), so I followed your previous suggestion

Issues in Kibana 4.1 tutorial tile map visualization: no time window selector, no geo_point compatible field

actually Iam using elk to analyse my network,
So to get the geo point I deleted all my indexes by using
/var/lib/elasticsearch/elastic/nodes/0/indices$ curl -XDELETE http://localhost:9200/logstash_netflow_cisco-2016.10.13*
{"acknowledged":true}xxx@xxx:/var/lib/elasticsearch/capelastic/nodes/0/indices$

XXX@XXX:/var/lib/elasticsearch/capelastic/nodes/0/indices$ curl -XPUT http://localhost:9200/logstash_netflow_cisco-2016.10.13 -d '

{
"mappings" : {
"log" : {
"properties" : {
"geo" : {
"properties" : {
"coordinates" : {
"type" : "geo_point"
}
}
}
}
}
}
}
';
{"error":{"root_cause":[{"type":"index_already_exists_exception","reason":"already exists","index":"logstash_netflow_cisco-2016.10.13"}],"type":"index_already_exists_exception","reason":"already exists","index":"logstash_netflow_cisco-2016.10.13"},"status":400}
Iam getting this error,please do let me know how to use curl XPUT to get Geo Point.
Please do provide valuable inputs,
Thanks,
Raj
