PAM Authentication for HttpFS

Complete the following steps to enable PAM authentication for HttpFS.

Add the following properties to the /opt/mapr/httpfs/httpfs-1.0/etc/hadoop/httpfs-site.xml file.

<property>
        <name>httpfs.hadoop.authentication.type</name>
        <value>multiauth</value>     
</property>      
          
<property>
        <name>httpfs.authentication.type</name>
        <value>multiauth</value>
</property>

Note: On secure clusters, the multiauth authentication is enabled by default.

Restart the HttpFS service.

sudo -u mapr /opt/mapr/httpfs/httpfs-1.0/sbin/httpfs.sh stop
sudo -u mapr /opt/mapr/httpfs/httpfs-1.0/sbin/httpfs.sh start

After restarting the service, run cURL with the PUT operation, as shown in this example:
Note: If HttpFS is configured with plain authentication through PAM, the cURL request must contain a username and password.
```
curl -X PUT "http://mapr:mapr@node1:14000/webhdfs/v1/tmp/example?op=mkdirs"
```
