Hongxu Ma created HAWQ-1485:
-------------------------------
Summary: Use user/password instead of credentials cache in Ranger
lookup for HAWQ with Kerberos enabled.
Key: HAWQ-1485
URL: https://issues.apache.org/jira/browse/HAWQ-1485
Project: Apache HAWQ
Issue Type: Sub-task
Components: Security
Reporter: Hongxu Ma
Assignee: Radar Lei
Fix For: 2.3.0.0-incubating
When used credentials cache:
Try error password in Ranger UI doesn't destroy the existed kerberos
credentials (created by last success kinit command)
It's a strange behavior to user.
So we should use user/password for kerberos authentication.
Core logic:
{code}
Properties props = new Properties();
if (connectionProperties.containsKey(AUTHENTICATION) &&
connectionProperties.get(AUTHENTICATION).equals(KERBEROS)) {
//kerberos mode
props.setProperty("kerberosServerName",
connectionProperties.get("principal"));
props.setProperty("jaasApplicationName", "pgjdbc");
}
String url = String.format("jdbc:postgresql://%s:%s/%s",
connectionProperties.get("hostname"), connectionProperties.get("port"), db);
props.setProperty("user", connectionProperties.get("username"));
props.setProperty("password", connectionProperties.get("password"));
return DriverManager.getConnection(url, props);
{code}
