`docker-compose` creates a docker network that can be found by running `docker network list`, e.g. `dockerhadoop_default`.

The configuration parameters can be specified in the hadoop.env file or as environmental variables for specific services (e.g. namenode, datanode etc.):
```
CORE_CONF_fs_defaultFS=hdfs://namenode:8020
```
CORE_CONF corresponds to core-site.xml. fs_defaultFS=hdfs://namenode:8020 will be transformed into:
