Hi Laurens,
Thank you for your response. I saw that reference under the “Miscellaneous Issues” section I made sure that the ‘node master’ was set to true. I verified that it was set properly curl localhost:9200/_nodes/stats/process?pretty [root@metron ~]# curl localhost:9200/_nodes/stats/process?pretty { "cluster_name" : "testl", "nodes" : { "ocKBNPXRS86UNA_XJosInA" : { "timestamp" : 1502457678195, "name" : "metron.<mydomain>.com", "transport_address" : "10.2.1.231:9300", "host" : "10.2.1.231", "ip" : [ "10.2.1.231:9300", "NONE" ], "attributes" : { "master" : "true" }, "process" : { "timestamp" : 1502457678196, "open_file_descriptors" : 260, "max_file_descriptors" : 65536, "cpu" : { "percent" : 0, "total_in_millis" : 23830 }, "mem" : { "total_virtual_in_bytes" : 6072864768 } } } } } Also I have verified that the mlockall is set to true. [root@metron ~]# curl http://localhost:9200/_nodes?filter_path=**.mlockall\&pretty { "nodes" : { "ocKBNPXRS86UNA_XJosInA" : { "settings" : { "bootstrap" : { "mlockall" : "True" } }, "process" : { "mlockall" : true } } } Frank From: Laurens Vets [mailto:laur...@daemon.be] Sent: Thursday, August 10, 2017 5:47 PM To: user@metron.apache.org Cc: Frank Horsfall <frankhorsf...@cunet.carleton.ca> Subject: Re: Problem with metron reference App Can you check in /etc/elasticsearch/elasticsearch.yml whether both node.data and node.master are true? I remember having to set this manually. Also check "expected_data_nodes" = "0" & "gateway_recover_after_data_nodes" = "1" in Ambari. It's part of the guide for CentOS 6, I might not have it copied over yet.

I have sued the single node install option outlined at https://cwiki.apache.org/confluence/display/METRON/Metron+0.4.0+with+HDP+2.5+bare-metal+install+on+Centos+7+with+MariaDB+for+Metron+REST I have read and worked through many of the suggestions regarding Elasticsearch etc but still cannot seem to get things working. Has anyone recently installed Metron using the above method and experienced similar difficulties? Kindest regards, Frank
