Subject [jira] [Created] (HADOOP-8857) hadoop.http.authentication.signature.secret.file should be created if the configured file does not exist

Eli Collins created HADOOP-8857:
-----------------------------------

             Summary: hadoop.http.authentication.signature.secret.file should be created if
the configured file does not exist
                 Key: HADOOP-8857
                 URL: https://issues.apache.org/jira/browse/HADOOP-8857
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.0.0-alpha
            Reporter: Eli Collins
            Priority: Minor


AuthenticationFilterInitializer#initFilter fails if the configured {{hadoop.http.authentication.signature.secret.file}}
does not exist, eg:

{noformat}
java.lang.RuntimeException: Could not read HTTP signature secret file: /var/lib/hadoop-hdfs/hadoop-http-auth-signature-secret
{noformat}

Creating /var/lib/hadoop-hdfs/hadoop-http-auth-signature-secret (populated with a string)
fixes the issue. Per the auth docs "If a secret is not provided a random secret is generated
at start up time.", which sounds like it means the file should be generated at startup with
a random secrete, which doesn't seem to be the case. Also the instructions in the docs should
be more clear in this regard.
