I am a newbie to Elasticsearch, so please be patient as I am troubleshooting a system that was not built by me. I have a single server running redis, elasticsearch, and logstash. Everything was running great on the system until it just started failing. When I look at Kibana, I see 'No index found' error message. When I try to look at the node status, it gives me "error":"IndexMissingException[[nodename] missing]","status":404
Where do I begin to troubleshoot this issue? When I look at the elasticsearch log I see:
org.elasticsearch.indices.InvalidTypeNameException: mapping type name is empty
followed by:
[Failed to start shard, message [IndexShardGatewayRecoveryException[[nodename-2015.01.17][4] failed to recover shard]; nested: IllegalArgumentException[No type mapped for [0]]
