------------------------------
Summary: HS2: SASL auth loads HiveConf
Key: HIVE-18905
URL: https://issues.apache.org/jira/browse/HIVE-18905
Project: Hive
Issue Type: Bug
Reporter: Gopal V
SASL authentication filter does a new HiveConf() for no good reason.
{code}
public static PasswdAuthenticationProvider
getAuthenticationProvider(AuthMethods authMethod)
throws AuthenticationException {
return getAuthenticationProvider(authMethod, new HiveConf());
}
{code}
The session HiveConf is not needed to do this operation & it can't be changed
after the HS2 starts up (today).
