Steps to reproduce:
When I do `$ sudo pacman -S elasticsearch` I get:
> warning: directory permissions differ on /etc/elasticsearch/
> filesystem: 750 package: 755

Also:
$ elasticsearch-keystore
/usr/bin/elasticsearch-keystore: line 3: /usr/bin/elasticsearch-cli: No such file or directory
$ elasticsearch-plugin
/usr/bin/elasticsearch-plugin: line 3: /usr/bin/elasticsearch-cli: No such file or directory
$ elasticsearch-sql-cli
zsh: command not found: elasticsearch-sql-cli
I think this is a weird path.

I assume I shouldn't run it as root so I change permissions.

I give up going down the rabbit hole. and uninstall it and try to use it with systemctl.
$ sudo pacman -Rn elasticsearch
$ sudo rm -rf /var/log/elasticsearch
$ sudo rm -rf /var/lib/elasticsearch
$ sudo rm -rf /etc/elasticsearch
$ sudo pacman -S elasticsearch
I removed all the files listed in pacman -Qkk elasticsearch and uninstall and install again and also do systemctl daemon-reload. and I when I run systemctl start elasticsearch.service I get:
Job for elasticsearch.service failed because a timeout was exceeded.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

and journalctl -xe gives:
