Atualizei recentemente minha máquina do Ubuntu14.04 para16.04. Estou enfrentando problemas ao usar oelasticsearch como um serviço. Euinstalado elasticsearch usando:

sudo apt-get install elasticsearch

Agorasudo service elasticsearch status comando mostra-me este resultado:

elasticsearch.service - LSB: Starts elasticsearch
   Loaded: loaded (/etc/init.d/elasticsearch; bad; vendor preset: enabled)
   Active: active (exited) since Sat 2016-07-30 18:28:13 BDT; 1h 19min ago

Jul 30 19:28:54 dimik systemd[1]: Started A search engine.
Jul 30 19:29:18 dimik systemd[1]: Started LSB: Starts elasticsearch.

Embora o Java esteja instalado na minha máquina e eu possa iniciar o servidor usando este comando.

sudo /usr/share/elasticsearch/bin/elasticsearch

Eu estou meio que preso aqui. Qualquer ajuda será apreciada.

Depois de configurarJAVA_HOME para erradicar o erro:
