-----------------------------------
Summary: Ranger-Admin enable security mode should not depend on
configuration logdir
Key: RANGER-1316
URL: https://issues.apache.org/jira/browse/RANGER-1316
Project: Ranger
Issue Type: Bug
Components: admin
Reporter: Qiang Zhang
Assignee: Qiang Zhang
Priority: Minor
Ranger-Admin enable security mode should not depend on configuration logdir,
in fact, it should depend on whether hadoop.security.authentication is kerberos.
If the logdir is null, even if Ranger-Admin is set to Kerberos authentication,
the Ranger-Admin would not enable security mode.
By the way, people who read the code will be confused,
because logdir has nothing to do with security of Ranger-Admin.
The code which have problem can be found in Java method EmbeddedServer.start():
{code}
if (getConfig("logdir") != null) {
String keytab = getConfig(ADMIN_USER_KEYTAB);
String principal = null;
......
if (getConfig(AUTHENTICATION_TYPE) != null &&
getConfig(AUTHENTICATION_TYPE).trim().equalsIgnoreCase(AUTH_TYPE_KERBEROS) &&
SecureClientLogin.isKerberosCredentialExists(principal, keytab)){
......
}
}
{code}
