I installed SHIELD yesterday. Connection is working, able to get data from ES cluster. During indexing, once in a while, I get "NoNodeAvailableException[None of the configured nodes are available" error. I'm using Bulk to index data. It works, then again our application throws this exception. Any ideas?
Specs:
Not using SSL
ES version 2.4.x
    Settings settings = Settings.settingsBuilder()
                                .put("cluster.name", "test_cluster")
    				.put("transport.ping_schedule", "5s")
                                .put("transport.sniff", true)
                                .put("action.bulk.compress", false)
    				.put("transport.tcp.compress", false)
                                .put("shield.user", "transporter:pass")
    				.build();
