Deploying elasticsearch via puppet ( puppet version 4.10.8) elasticsearch module (elastic-elasticsearch (v5.4.3)) , i got te below errors

please can anyone put me in the right direction on how to resolve this.
i am just a beginner

Hi @shoshoro99, this is likely due to the way you're passing in jvm_options to your init defaults. Rather than defining jvm_options in that way, use the supported jvm_options parameter to control those settings you're trying to control. Does that change anything?

PS: I edited your post to wrap Puppet's output in code blocks, considering doing so yourself in the future as it makes reading code output much easier. :slight_smile:

thanks for our reply, i did apply your suggestion, but got different error listed below

    Info:        /Stage[main]/Analytic::Elasticsearch/Elasticsearch::Instance[elastic1]/Elasticsearch::Service[elastic1]/Elasticsearch::Service::Systemd[elastic1]/Service[elasticsearch-instance-elastic1]: Unscheduling refresh on Service[elasticsearch-instance-elastic1]

@shoshoro99 a timeout would mean that in attempting to manage your index settings, Puppet could not reach Elasticsearch in time to apply the settings for the index. If you run that manifest a second time, does the catalog apply cleanly? If so, that would mean that Elasticsearch simply took a long time to come up, and you can deal with that in the future by using the timeout parameter on elasticsearch::index resources.

thanks for your reply tylerj, i tried API_timeout increase from 10 to 50, i still get same error could not connect to local host on 9200 error, also what i have observed is that i see two services in this path /usr/lib/systemd/system/elasticsearch.services and elasticsearch-elastic1.service ,the latter is instance based services (where elastic1 is my instance name) i am confused. pardon me i am just a begginer with elasticsearch and puppet module elastic-elasticsearch --version 6.1.0

6

@shoshoro99 you are correct, the Puppet module manages separate instances for Elasticsearch, so elasticsearch.service will be unused on the target system, and Puppet will manage and start elasticsearch-elastic1 instead.

Regarding the timeout issue, is the Elasticsearch API up and available on the system after Puppet runs? That is, does a simple curl localhost:9200 get a response? You may also want to check if it's listening with something like netstat -lpnt | grep 9200.

thanks, but when i start elasticsearch-elsatic1.service, i got below error and there is this specific line in bold <asticsearch[5059]: **Error: Could not find or load main class 2g>.

Hint: Some lines were ellipsized, use -l to show in full.

And when i check curl http://localhost:9200, it return below error
curl: (7) Failed connect to localhost:9200; Connection refused
please advice what next should i check.

Error: Could not find or load main class 2g is something I haven't seen before. What version of Java are you running on this machine?

$ java -version
9

here is my java version installed
[root@elastic1 ~]# java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
also i used puppet to deploy this instance
puppet master and agent version
4.10.9

It's definitely a strange error, I'm not sure where it may be originating from. I'd perhaps also check Elasticsearch's logs (which are in /var/log/elasticsearch by default) and also check the contents of /etc/sysconfig/elasticsearch-elastic1.

The ES_JAVA_OPTS line in /etc/sysconfig/elasticsearch-elastic1 is the problem. If you remove that, Elasticsearch should start successfully.

13

thanks it running , but when puppet agent runs again , it goes back to start given errors , as i have shown it before in my manifest i did not set ES_JAVA_OPTS, i believe somehow in the elasticsearch puppet module has some configuration that is setting this options. would kindly take a look.
below is my elasticsearch.pp

class { 'elasticsearch':
  manage_repo  => true,
  repo_version => '6.x',
  version  => '6.1.1',

}
elasticsearch::instance { $hostname:
  status  => enabled,
  config        => {
          'cluster.name' => 'analytics',
           'node.name' => $fqdn,
           'node.master' => true,
           'node.data' => false,
           'network.host' => [ $::ipaddress ],
           'network.bind_host'=> "0",
           'http.port' => '9200-9300',
           'bootstrap.memory_lock' => true ,
           'discovery.zen.ping.multicast.enabled' => false,
           'discovery.zen.ping.unicast.hosts' => ["10.0.0.64", "10.0.0.65"], # Configuration hash
           'discovery.zen.minimum_master_nodes' => '1',
                   },
  jvm_options => [
                  '-Xms2g',
                  '-Xmx2g'
                 ],
  init_defaults => {

        'MAX_OPEN_FILES' => 65535,
        'MAX_LOCKED_MEMORY' => 'unlimited',
        'MAX_MAP_COUNT' => 262144,
                 }, # Init defaults hash

}



}
14

The module doesn't manage ES_JAVA_OPTS in the init defaults file; the only values it will manage are those defined in your init_defaults parameter. Perhaps Elasticsearch is failing to start due to a different error?
