Elasticsearch server starts with following exception

I am new to Elasticsearch and AWS ec2 and my elasticsearch server (deployed over AWS EC2 instance) is starting with following exception:

[2015-01-23 06:36:44,919][ERROR][marvel.agent] [elasticnode] exporter [es_exporter] has thrown an exception:
java.lang.NullPointerException
        at org.elasticsearch.marvel.agent.Utils.extractHostsFromHttpServer(Utils.java:90)

        at org.elasticsearch.marvel.agent.AgentService$ExportingWorker.run(AgentService.java:225)
        at java.lang.Thread.run(Thread.java:745)

I am not able to figure out the exact reason for this. Please help me.

Thanks

Marvel tries to connect to elasticsearch before it is fully initialized. You can safely ignore that error unless it persists.
