Enable SSL for HttpFS
Use the following steps to configure HttpFS to work over SSL.
- Edit the - httpfs-env.shscript in the configuration directory and set- HTTPFS_SSL_ENABLEDto- true.- In addition, the following 2 properties can be defined (shown here with default values): - HTTPFS_SSL_KEYSTORE_FILE=$HOME/.keystore
- HTTPFS_SSL_KEYSTORE_PASS=password
 
- In the HttpFS - tomcat/confdirectory, replace the- server.xmlfile with the- ssl-server.xmlfile.
- Create an SSL certificate for the HttpFS server. As the httpfs Unix user, use the Java keytool command to create the SSL certificate: - $ keytool -genkey -alias tomcat -keyalg RSA - You will be asked a series of questions in an interactive prompt. It will create the keystore file, which will be named - .keystoreand located in the httpfs user home directory.- The password you enter for “keystore password” must match the value of the HTTPFS_SSL_KEYSTORE_PASS environment variable set in the - httpfs-env.shscript in the configuration directory.- The answer to “What is your first and last name?” (i.e. “CN”) must be the host name of the machine where the HttpFS Server will be running. 
- Start HttpFS. It should work over HTTPS. 
- Utilizing the Hadoop FileSystem API or the Hadoop FS shell, use the swebhdfs:// scheme. Make sure the JVM is picking up the truststore containing the public key of the SSL certificate if you are using a self-signed certificate.
