I am getting an error while installing elasticsearch-5.4.0. I already have elasticsearch-2.3.3 in my system.
Disk space is 29 GB free. What will be the issue?

It's a warning.

If you are doing tests, you can disable the watermark checks.

I am planning to work on 'X-Pack'. For that ES 5.4 is required,right?. So I am installing ES 5.4. What is this watermark checks for?

No. You are not forced to use xpack.
Xpack is a plugin which adds security, alerting, monitoring, reporting, graph and machine learning. So if you don't need any of those features, you don't need xpack.

About watermarks, read https://www.elastic.co/guide/en/elasticsearch/reference/5.4/disk-allocator.html

I need to use graph in X-Pack.
Is it possible to install ES2.3.3. and ES 5.4 together in a system? I am new in ES, that's why I am asking such questions. Please help
