Configure WebHCat server to use SSL encryption

You can configure WebHCat REST-API to use SSL (Secure Sockets Layer) encryption. The following WebHCat properties are added to enable SSL.

templeton.use.ssl
Default value: false
Description: Set this to true for using SSL encryption for WebHCat server

templeton.keystore.path
Default value: <empty string>
Description: SSL certificate keystore location for WebHCat server

templeton.keystore.password
Default value: <empty string>
Description: SSL certificate keystore password for WebHCat server

Description: SSL Versions to disable for WebHCat server

templeton.host
Default value: 0.0.0.0
Description: The host address the WebHCat server will listen on.

Modifying the webhcat-site.xml file

Configure the following properties in the webhcat-site.xml file to enable SSL encryption on each node where WebHCat is installed:

<!-- WebHCat SSL -->
<property>
  <name>templeton.use.ssl</name>
  <value>true</value>
</property>

<property>
  <name>templeton.keystore.path</name>
  <value>/path/to/ssl_keystore</value>
</property>

<property>
  <name>templeton.keystore.password</name>
  <value>password</value>
</property>

Example: To check status of WebHCat server configured for SSL encryption use following command

curl -k 'https://<user>:<password>@<host>:50111/templeton/v1/status'

replace <user> and <password> with valid user/password. Replace <host> with your host name.
