public final class SimpleKdcServerUtil
extends Object

Utility for running SimpleKdcServer. Kerby KDC server is favored over Hadoop org.apache.hadoop.minikdc server which has support in the HBaseTestingUtility at #setupMiniKdc. The Kerby KDC Server came in with HBASE-5291. Its preferred. Less baggage.

getRunningSimpleKdcServer

public static org.apache.kerby.kerberos.kerb.server.SimpleKdcServer getRunningSimpleKdcServer(File testDir,
 Supplier<Integer> randomPortGenerator)
                                                                                       throws org.apache.kerby.kerberos.kerb.KrbException,
IOException

Returns a running kdc server. Use this method rather than start the SimpleKdcServer yourself because it takes care of BindExceptions which can happen even though port-picking is random (between the choice of port number and bind, it could have been used elsewhere).

Returns:

A SimpleKdcServer on which 'start' has been called; be sure to call stop on this instance when done.

Throws:

org.apache.kerby.kerberos.kerb.KrbException

IOException

getRunningSimpleKdcServer

static org.apache.kerby.kerberos.kerb.server.SimpleKdcServer getRunningSimpleKdcServer(File testDir,
 Supplier<Integer> randomPortGenerator,
 boolean portClash)
                                                                                throws org.apache.kerby.kerberos.kerb.KrbException,
IOException

Internal method for testing.

Parameters:

portClash - True if we want to generate BindException (for testing).

Returns:

A running SimpleKdcServer on loopback/'localhost' on a random port

Throws:

org.apache.kerby.kerberos.kerb.KrbException

IOException
