Haohui Mai created HADOOP-11748:
-----------------------------------
Summary: Secrets for auth cookies can be specified in clear text
Key: HADOOP-11748
URL: https://issues.apache.org/jira/browse/HADOOP-11748
Project: Hadoop Common
Issue Type: Bug
Reporter: Haohui Mai
Priority: Critical
Based on the discussion on HADOOP-10670, this jira proposes to remove
{{StringSecretProvider}} as it opens up possibilities for misconfiguration and
security vulnerabilities.

My understanding is that the use case of inlining the secret is never
supported. The property is used to pass the secret internally. The way it works
before HADOOP-10868 is the following:
* Users specify the initializer of the authentication filter in the
configuration.
* AuthenticationFilterInitializer reads the secret file. The server will not
start if the secret file does not exists. The initializer will set the property
if it read the file correctly.
*There is no way to specify the secret in the configuration out-of-the-box –
the secret is always overwritten by AuthenticationFilterInitializer.
