Logstash's Elasticsearch input plugin timeout

I'm trying to use logstash to extract all records from ES (very small records) and populate them into rabbitmq. I wanted to see what the fastest I could go so I didn't set up any persistence/durability so disk IO should not be a problem. ES timed out as a result and I'm not sure of how to go about resolving this issue.

Here's the exact error message:

A plugin had an unrecoverable error. Will restart this plugin.
Plugin: <LogStash::Inputs::Elasticsearch hosts=>["", "", "", "", "", "", "", "", ""], index=>"com-initial", scroll=>"1m", size=>1000, codec=><LogStash::Codecs::JSON charset=>"UTF-8">, query=>"{"query": { "match_all": {} } }", scan=>true, docinfo=>false, docinfo_target=>"@metadata", docinfo_fields=>["_index", "_type", "_id"], ssl=>false>
Error: Timeout::Error {:level=>:error}

Any ideas on how to keep it from timing out?

Thanks in advance!
