Subject [jira] [Created] (HADOOP-11567) Refresh HTTP Authentication secret without restarting the server
Date Mon, 09 Feb 2015 23:28:35 GMT
Benoy Antony created HADOOP-11567:
-------------------------------------

             Summary: Refresh HTTP Authentication secret without restarting the server
                 Key: HADOOP-11567
                 URL: https://issues.apache.org/jira/browse/HADOOP-11567
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 2.6.0
            Reporter: Benoy Antony
            Assignee: Benoy Antony


The _AuthenticationFilter_ uses the secret read from a file specified via hadoop.http.authentication.signature.secret.file
to sign the cookie containing user authentication information.
The secret is read only during initialization and hence needs a restart to update the secret.

ZKSignerSecretProvider can be used to rotate the secrets without restarting the servers, but
it needs a zookeeper setup.
The jira is to refresh secret by updating the file.
