Error while transferrring data from one ES cluster to another

I'm using to transfer data from one elasticsearch cluster to another using logstash configuration above.
Getting this error while running the logstash:

Host Cluster: Elasticsearch 1.1.1
Destination Cluster: Elasticsearch 1.5.2

Logstash Script

input {
     elasticsearch {
                host => "localhost"
                index => "logstash-*"
     }
}

output {
      elasticsearch {
                host => "xyz.com"
                protocol => "http"
                index => "logstash-%{+YYYY.MM.dd}"
      }
}

Error

A plugin had an unrecoverable error. Will restart this plugin.
  Plugin: <LogStash::Inputs::Elasticsearch host=>"1ocalhost", index=>"logstash-enabler-2015.07*", query=>"*", scroll=>"1m">
  Error: gethostbyname: name or service not known {:level=>:error}

Thanks.

You have a bad hostname there somewhere.
