Nicolas Liochon created HBASE-14580:
---------------------------------------
Summary: Make the HBaseMiniCluster compliant with Kerberos
Key: HBASE-14580
URL: https://issues.apache.org/jira/browse/HBASE-14580
Project: HBase
Issue Type: Improvement
Components: security, test
Affects Versions: 2.0.0
Reporter: Nicolas Liochon
Assignee: Nicolas Liochon
Fix For: 2.0.0
Whne using MiniKDC and the minicluster in a unit test, there is a conflict
causeed by HBaseTestingUtility:
{code}
public static User getDifferentUser(final Configuration c,
final String differentiatingSuffix)
throws IOException {
// snip
String username = User.getCurrent().getName() +
differentiatingSuffix; <==================== problem here
User user = User.createUserForTesting(c, username,
new String[]{"supergroup"});
return user;
}
{code}
This creates users like securedUser/[email protected], and this does
not work.
My fix is to return the current user when Kerberos is set. I don't think that
there is another option (any other opinion?). However this user is not in a
group so we have logs like 'WARN [IPC Server handler 9 on 61366]
security.UserGroupInformation (UserGroupInformation.java:getGroupNames(1521)) -
No groups available for user securedUser' I'm not sure of its impact.
[~apurtell], what do you think?
