-## Configuring Flink with Hadoop Classpaths
+## Configure Hadoop
+
+You can reference Hadoop configuration by setting the environment variable
`HADOOP_CONF_DIR`.
+
+```sh
+HADOOP_CONF_DIR=/path/to/etc/hadoop
+```
+
+Referencing the HDFS configuration in the [Flink configuration]({{
site.baseurl }}/ops/config.html#hdfs) is deprecated.
+
+Another way to provide the Hadoop configuration is to have it on the class
path of the Flink process, see more details below.
