ElasticSearch on Raspberry Pi exited

Question

I'm trying to run ElasticSearch on Raspbian on my Raspberry Pi 3. After simply running sudo apt install elasticsearch it installed A LOT of things, and then I tried sudo service elasticsearch status, which gives the following result:

$ sudo service elasticsearch status
● elasticsearch.service - LSB: Starts elasticsearch
   Loaded: loaded (/etc/init.d/elasticsearch)
   Active: active (exited) since Thu 2017-02-16 23:28:52 UTC; 1s ago
  Process: 6022 ExecStop=/etc/init.d/elasticsearch stop (code=exited, status=0/SUCCESS)
  Process: 6063 ExecStart=/etc/init.d/elasticsearch start (code=exited, status=0/SUCCESS)

I don't really get what this active (exited) means. I tried getting the ElasticSearch version, but that also failed:

$ curl -XGET 'http://localhost:9200'
curl: (7) Failed to connect to localhost port 9200: Connection refused

Does anybody know what is wrong and how I can proceed from here?

Answer 1

Ok, in the end I managed to get it running. I had to install java 8

sudo apt-get purge openjdk-7-jdk
sudo apt-get install openjdk-8-jdk

and set the memory maximum lower by opening /etc/elasticsearch/jvm.options and replacing

-Xms2G
-Xmx2G

with

-Xms256M
-Xmx256M

Restarting ES (sudo service elasticsearch start) solved it for me.

I hope this helps someone else as well. Regardless, I wish you a beautiful day!
