Hi,
I've installed Metron 0.7.0 on CentOS7 using Ambari.
I've got 8 nodes of which master is the Ambari master and slave5 is the Metron
node.
Metron node has all the Metron services on it plus one ElasticSearch Master and
one ElasticSearch Data Node as per
https://community.hortonworks.com/articles/60805/deploying-a-fresh-metron-cluster-using-ambari-serv.html
Ambari is showing no issues, but when I open Kibana, it shows "Elasticsearch
plugin is red".
Checking ES gives me:
# curl -X GET "slave5:9200/_cat/indices"
{"error":{"root_cause":[{"type":"master_not_discovered_exception...
Checking the logs gives me:
# tail /var/log/elasticsearch/metron.log
...not enough master nodes discovered during pinging (found [[]], but needed
[-1])...
# tail /var/log/kibana/kibana.log
...No living connections...
...Unable to revive connection: http://slave5:9200/...
...Service Unavailable...
Any ideas how to resolve these errors?
If you can't answer that, please consider the following:
Where else should I look for errors?
Is one ElasticSearch Master and one ElasticSearch Data Node correct?
What is the difference between Master and Data Node - this doesn't seem to make
much sense from an ElasticSearch pov?
Thanks,
Tobin
