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.
