Zhijie Shen commented on HADOOP-11754:
--------------------------------------
I'm not sure why we want to prevent using the random secret in the secure mode.
As is mentioned above, it's an incompatible semantics change, which will break
RM web interface and timeline server secure deployment. I don't think we have
conveyed this secure setup requirement of secret file to the users (e.g.,
Ambari). [~vinodkv], any idea?
{code}
277 // Fallback to RandomeSignerSecretProvider if the secret file is
278 // unspecified in insecure mode
279 if (!isSecurityEnabled && config.getProperty(SIGNATURE_SECRET_FILE)
==
280 null) {
281 name = "random";
282 }
{code}
{code}
289 if (!isSecurityEnabled) {
290 LOG.info("The signature secret of the authentication filter
is " +
291 "unspecified, falling back to use random
secrets.");
292 provider = new RandomSignerSecretProvider();
293 provider.init(config, servletContext, validity);
294 } else {
295 throw e;
296 }
{code}
