Github user JonathanRider commented on the issue: https://github.com/apache/incubator-metron/pull/379 Just ran it on quickdev where I set the es.host in the global json file to "node2,node1" where node2 doesn't exist as it is a single node vagrant. Using my patch, it writes to ES without a problem as it fails to use node2, so it switches to node1. I then compiled master and did the same thing and received this error since node2 doesn't exist and it fails to use the second host.: 2016-12-01 21:41:18.942 o.a.m.w.BulkWriterComponent [ERROR] Failing 5 tuples org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{10.120.164.190}{node2/10.120.164.190:9300}]
