Laxman created HADOOP-8555:
------------------------------
Summary: Incorrect Kerberos configuration
Key: HADOOP-8555
URL: https://issues.apache.org/jira/browse/HADOOP-8555
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.0.0-alpha, 2.0.1-alpha, 3.0.0
Reporter: Laxman
When keytab is given ticket cache should not be considered.
Following configuration tries to use ticket cache even when keytab is
configured. We need not configure ticket cache here.
org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler.KerberosConfiguration.getAppConfigurationEntry(String)
{code}
options.put("keyTab", keytab);
options.put("principal", principal);
options.put("useKeyTab", "true");
options.put("storeKey", "true");
options.put("doNotPrompt", "true");
options.put("useTicketCache", "true");
options.put("renewTGT", "true");
options.put("refreshKrb5Config", "true");
options.put("isInitiator", "false");
String ticketCache = System.getenv("KRB5CCNAME");
if (ticketCache != null) {
options.put("ticketCache", ticketCache);
}
{code}
