ElasticSearch on Raspberry Pi exited
Ok, in the end I managed to get it running. I had to install java 8
sudo apt-get purge openjdk-7-jdksudo apt-get install openjdk-8-jdkand set the memory maximum lower by opening /etc/elasticsearch/jvm.options and replacing
-Xms2G-Xmx2Gwith
-Xms256M-Xmx256MRestarting ES (sudo service elasticsearch start) solved it for me.
I hope this helps someone else as well. Regardless, I wish you a beautiful day!
At time of posting, installing through apt-get install elasticsearch on latest Raspbian release installs Elasticsearch 1.7 (which does not use /etc/elasticsearch/jvm.options)
Go to https://www.elastic.co/downloads/elasticsearch and get the link for the .deb package. Then install it with the following:
cd /home/piwget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.6.1.debdpkg -i elasticsearch-6.6.1.debOnce you've done that you'll be able to edit /etc/elasticsearch/jvm.options and then start elasticsearch.
