Bug description

The README recomends: when configuring Elasticsearch's memory usage, you can modify it by setting jvm_options

class { 'elasticsearch':
  jvm_options => [
    '-Xms4g',
    '-Xmx4g'
  ]
}

This adds -Xms4g and -Xmx4g in the file /etc/elasticsearch/jvm.options.d/jvm.options. But this configuration is overwritten by the contents of /etc/elasticsearch/jvm.options, therefore nullifying its effects.

[phaedriel]

the module don't touch this file /etc/elasticsearch.jvm.options now (elasticsearch version 7.7.0+). https://www.elastic.co/guide/en/elasticsearch/reference/master/advanced-configuration.html#set-jvm-options.

A solution it 's to restore/rewrite the original file /etc/elasticsearch.jvm.options
