Hi All ,

I am trying to export elasticsearch index data to CSV using logstash , Below is my configuration :-

`
input {
elasticsearch {
hosts => "localhost:9200"
index => "index_name"
query => '
{
"query": {
"match_all": {}
}
}
'
}
}
output {
csv {
# elastic field name
fields => ["filed1","filed2"]
# This is path where we store output.
path => "/etc/logstash/scrap/index_name.csv"
}
}
`

However instead of whole data only partial data is coming in csv ,Below is output of log file :-

[INFO] 2019-08-08 13:27:01.368 [Ruby-0-Thread-22@[main]\>worker18: :1] csv - Opening file {:path=\>"/etc/logstash/scrap/index\_name.csv"}  
[INFO] 2019-08-08 13:30:29.187 [Ruby-0-Thread-26@[main]\>worker22: :1] csv - Closing file /etc/logstash/scrap/index\_name.csv  
[INFO] 2019-08-08 13:30:30.776 [Ruby-0-Thread-24@[main]\>worker20: :1] csv - Opening file {:path=\>"/etc/logstash/scrap/index\_name.csv"}  
[INFO] 2019-08-08 13:31:56.951 [[main]-pipeline-manager] pipeline - Pipeline has terminated {:pipeline\_id=\>"main", :thread=\>"#\<Thread:0x4b4d65bb run\>"}

Multiple opening file and closing file is there and this might be the issue , Please suggest how to fix this issue.
