Hi  
I use logstash to import data from a csv file. It was successful but makes over plus columns that not exists in my data.  
my config file is  
indent preformatted text by 4 spaces  
input {  
file {  
path =\> "C:/Data/booking/booking.csv"  
start\_position =\> "beginning"  
#sincedb\_path =\> "/dev/null"  
}  
}  
filter {  
csv {  
separator =\> "|"  
columns =\> ["hotelId","HotelName","City"]  
remove\_field =\> ["host", "message", "path", "@timestamp", "@version"]   
}  
}  
output {  
elasticsearch {  
hosts =\> "localhost"  
index =\> "booking"  
document\_type =\> "hotel"  
}  
stdout {}  
}

And there is my index info:  
indent preformatted text by 4 spaces  
{  
"booking" : {  
"aliases" : { },  
"mappings" : {  
"hotel" : {  
"properties" : {  
"City" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"HotelName" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"column4" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"column5" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"column6" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"column7" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"column8" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
"hotelId" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
}  
}  
}  
},  
"settings" : {  
"index" : {  
"creation\_date" : "1543999132912",  
"number\_of\_shards" : "5",  
"number\_of\_replicas" : "1",  
"uuid" : "\_Xq0aXnZSFyOD3pEYj2nCg",  
"version" : {  
"created" : "6050199"  
},  
"provided\_name" : "booking"  
}  
}  
}  
}
