Answer 1

You cannot delete a mapping type, hence why your first query doesn't work.

You can only delete an index

curl -XDELETE http://10.1.2.10:9200/g_visitor

If you want to use the delete-by-query approach, you can do so, but you need to install the plugin first

sudo bin/plugin install delete-by-query

Then you can use the plugin like this by calling the _query endpoint (not _delete_by_query!!):

curl -XDELETE 'http://10.1.2.10:9200/g_visitor/gvisitor/_query?conflicts=proceed' -d '{
    "query" : { 
        "match_all" : {}
    }
}'
