Got it! I am using the ES java client, which becomes member of the ES cluster. The start order is essential, when starting the client before the server, it occupies the port 9200. There server will use the next free port. So localhost:9200 will reach the client, which has no plugin installed. An invalid plugin url will result in empty page.
Some days ago I updated my 2-node ES Cluster to 1.3.4. Since the update the > installed plugins sometimes are not applicable and for > http://localhost:9200/_plugin/head returns an empty page. > > This effect is seen very often after restarting a node, e.g. after > SHUTDOWN or simply killing the server process.
