## Biến môi trường `PATH`

Có một biến môi trường **đặc biệt** được gọi là **`PATH`** được sử dụng bởi các hệ điều hành (Linux, macOS, Windows) nhằm tìm các chương trình để thực thi.

Let's take for example a set of 12 compute nodes with an aggregate memory of _1.2TiB_, we need to do following settings for optimal results. Add the following optimal entries for _core-site.xml_ to configure _s3a_ with **MinIO**. Most important options here are

```
cat ${HADOOP_CONF_DIR}/core-site.xml | kv-pairify | grep "mapred"
