How to load CSV file in logstash

I am trying to load CSV file in logstash but it is not reading the file and not creating the index in elasticsearch

My Config file
input {

file {
    type => "csv"
    path => "/root/installables/*.csv"
    start_position => beginning


filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
output {
elasticsearch {
hosts => localhost
index => "client"
Could anybody tell how to load CSV file in logstash?

For one-shot imports of files where you don't need to support restarts of Logstash while the file is being processed I suggest you set sincedb_path => "/dev/null" for the file input or use the stdin input.

You should consult the file input documentation and read about sincedb files, because that's what's going on here; Logstash is waiting for more data to be added to the end of the file.

This question is very frequently asked so you'll find additional reading in the archives.

I already tried placing since_db , it is still now working!

If you enable verbose logs by starting Logstash with --verbose you'll find more clues as to what's happening. We need those clues to debug the issue further.
