Configuring HttpFS to use SSL

Configure the HttpFS Server to use SSL (HTTPS)

Stop HttpFS by running
```
sudo /sbin/service hadoop-httpfs stop
```
To enable SSL, change which configuration the HttpFS server should work with using the alternatives command.
Note: The alternatives command is only available on RHEL systems. For SLES, Ubuntu and Debian systems, the command is update-alternatives.
For RHEL systems, to use SSL:
```
alternatives --set hadoop-httpfs-tomcat-conf /etc/hadoop-httpfs/tomcat-conf.https
```
Important:
The HTTPFS_SSL_KEYSTORE_PASS variable must be the same as the password used when creating the keystore file. If you used a password other than password, you'll have to change the value of the HTTPFS_SSL_KEYSTORE_PASS variable in /etc/hadoop-httpfs/conf/httpfs-env.sh.
Start HttpFS by running
```
sudo /sbin/service hadoop-httpfs start
```

Connect to the HttpFS Web UI using SSL (HTTPS)

Use https://<httpfs_server_hostname>:14000/webhdfs/v1/ though most browsers should automatically redirect you if you use http://<httpfs_server_hostname>:14000/webhdfs/v1/
