Logstash ElasticSearch IOException :

Hi all,

I'm trying to use Logstash and ElasticSearch for the first time and I get some troubles doing so.

ES version : 1.7.2 (also tried with 2.0.0 beta2 for the same result).
Logstash version : 1.5.4

The context : I'm using the logstash JDBC plugin and when trying to index a table content in ES, I have an exception :

    [2015-09-20 13:08:42,238][WARN ][http.netty               ] [Willie Lumpkin] Caught exception while handling client http traffic, closing connection [id: 0x729e1f0d, / => /]

My Logstash conf file is as follow :

input {
    jdbc {
        # Postgres jdbc connection string to our database, mydb
        jdbc_connection_string => "jdbc:postgresql://localhost:5432/Dell"
        # The user we wish to execute our statement as
        jdbc_user => "postgres"
		# The password
		jdbc_password => "****"
        # The path to our downloaded jdbc driver
        jdbc_driver_library => "postgresql-9.1-901.jdbc4.jar"
        # The name of the driver class for Postgresql
        jdbc_driver_class => "org.postgresql.Driver"
        # our query
        statement => "SELECT * from products"
output {
	stdout { codec => json_lines }
    elasticsearch {
        protocol => http
        index => "products"
        document_type => "product"
        document_id => "%{uid}"
        host => ""

If I run a

curl localhost:9200/_cluster/health/?pretty

before indexing, the cluster status is green. After trying to index, it turns yellow.

  "cluster_name" : "elasticsearch",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 10,
  "active_shards" : 10,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 10,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0

The stdout output for Logstash works fine.

Thanks for your help.

PS : if I run any command on Logstash, it works but I get the following message :

io/console not supported; tty will not be manipulated

I'm answering myself.
I created a VM with Linux Mint on it. I copied ES and Logstash folders on this VM and tried to run it. It worked !
My next concern is to have Kibana running with my datas.
