Logstash input Elasticsearch plugin error

[kabali12345]

Hi all....
Here i am trying to load elasticsearch data into anther elasticsearch or a file
but the problem is
in my input elasticsearch index i have 1000 docs
when it comes to output elasticsearch index i am getting more docs because
input elasticsearch continuously repeating ingesting the same data
here is my conf

input {
 elasticsearch {
    hosts => "192.168.1.75:9200"
    index => "titanic"
#query => '{ "query":{"range" : {    "@timestamp" : {        "gt" : "now-400d"   } } }, "sort": [ {"PassengerId" : {"order" : "asc"}} ] }'

#    query => '{ "query": { "match_all": {} } }'
size => 1000
    scroll => "1m"
    type => "logs"
codec => "json"

 }

}

output {
    elasticsearch {
        index => "atitanic"
        #template_overwrite => true
        #template => "/tmp/current-loc.json"
      #  document_type => "%{type}"
        #document_id => "%{_id}"
        hosts => ["http://192.168.1.59:9233"]
    }
    stdout {codec => rubydebug}
}

i am getting this error on consol
