The conf file is below:

input{

file{
path =>"S:\ELK\data\studymig.csv"
start_position => "beginning"
sincedb_path => "\dev\null"
}

}

filter {
csv {
separator =>","
columns =>["a","b","c","d","e"]
}

}
output {
elasticsearch {
hosts=>"localhost"
index =>"studymig"
document_type =>"study_status"
}
stdout {
codec => rubydebug
}
}

If you are running on Windows and you want to suppress the use of a persistent sincedb then set

sincedb_path => "NUL"

not /dev/null.
