How can I connect from a remote server to a CrateDB node using crash?

If you change it assumes that you’re using CrateDB for production and enforces some Bootstrap Checks to ensure CrateDB is suitably configured.

When using the package-based setup flavor for Debian or Ubuntu or Red Hat or CentOS, the CrateDB startup script uses Environment variables from the /etc/default/crate file.

or you set it in the console with e.g.

export CRATE_HEAP_SIZE=4g  

I think we might need to adjust the notes a little:

I am sorry that you have such a bad experience. Me and my team are currently working to make the start with CrateDB as easy as possible.
