> 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.
