Hi everyone,
I'm very new to elasticsearch and I'm facing my first red status.
My cluster has 4 data nodes (3 master candidates). Everything was perfectly working until now (so I assume my conf files are ok).
What happened :
(1) I sent log data to elasticsearch using logstash
(2) This was taking forever so I decided to stop the process
(3) Status went red
This must be a shard problem ... but I can't even see what's my cluster health. I get the error "master_not_discovered_exception".
Do you know how can I debug my cluster ? I don't care loosing the data if necessary ...
Thank you very much
Maxime
