elasticsearch - LogStash failed action with response of 500, dropping action -

I'm trying to configure LogStash to send events to view a file and elasticsearch server.

When I start the logout in the output stdout, it runs fine:

  stdout {codec = & gt; Rubydebug}  

But when I add elasticsearch output:

  elasticsearch {cluster = & gt; 'Myclustername' host = & gt; 'Mayp' node_name = & gt; The 'Aragorn'}  

Logstas start

But when the messages begin to arrive, anything in fact L Is not sent to asticsearch and these logstash outputs start displaying in:

  Warning: [Aragon] Message (response) [28] Handler org.elasticsearch.action.sup Port.master.TransportMasterNodeOperationAction not fully read for $ 6 @ 17b 531e, error [true], resetting 16 March 2015 3:44:54 PM org.elasticsearch.transport.netty.MessageChannelHandler Receives Message Warning: [Aragorn] Not fully read (response) handler for message [29] org.elasticsearch.

and

  {: timestamp = & gt; "2015-03-16T15: 44: 54.377000 + 0100",: Message = & gt; Unsuccessful action with feedback of 500, skipping action ...  

(The above message is too long but does not seem to include any useful diagnostics)

What could be wrong?
