Nope, it's just normal cluster tasks occuring.

You must be using node client to talk to elasticsearch which just recognized logstash as it's non data node through zen discovery. Check elasticsearch output configuration settings in logstash conf file. It's normal and not an issue as mentioned by Mark.

"Node client"? are you referring to head or marvel plugin?
here is logstash output plugin configuration.
elasticsearch {
cluster => "esearch02"
index => "test-%{+YYYY.MM.dd}"
workers => 4

As far as I know Cluster setting in above configuration also uses node client to connect to ES. Either you specify protocol => "node" or provide cluster => "esearch02" will have same effect.
