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
}
}
}

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.

Hello,
I am currently working through the adding a new telemetry event located 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
Everything seems to be going well until I get to the last step ‘Verify Events
are indexed’
The index does not display.
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
