====== Increase Big Data Service RAM ======

By default, the big data service assumes a modest RAM allowance. However, this can be increased for better
performance.

Consider increasing memory allocation up to up to 1/3rd of a server’s available RAM (no more than 32GB)

1. Check available server memory to determine available RAM

4. Under Java properties, increase the Initial and Maximum memory pools.

In this example, we’ve increased it from 1024MB to 2048MB.

Click apply and close the properties window.
