• Type: Sub-task
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.3.0
• Hadoop Flags: Reviewed

Release Note

Add new HTTP policy configuration. Users can use "dfs.http.policy" to control the HTTP endpoints for NameNode and DataNode. Specifically, The following values are supported:
- HTTP_ONLY : Service is provided only on http
- HTTPS_ONLY : Service is provided only on https
- HTTP_AND_HTTPS : Service is provided both on http and https

hadoop.ssl.enabled and dfs.https.enabled are deprecated. When the deprecated configuration properties are still configured, currently http policy is decided based on the following rules:
1. If dfs.http.policy is set to HTTPS_ONLY or HTTP_AND_HTTPS. It picks the specified policy, otherwise it proceeds to 2~4.
2. It picks HTTPS_ONLY if hadoop.ssl.enabled equals to true.
3. It picks HTTP_AND_HTTPS if dfs.https.enable equals to true.
4. It picks HTTP_ONLY for other configurations.
