Laxman commented on HADOOP-8555:
--------------------------------
This code should be
{code}
options.put("keyTab", keytab);
options.put("principal", principal);
options.put("useKeyTab", "true");
options.put("storeKey", "true");
options.put("doNotPrompt", "true");
options.put("refreshKrb5Config", "true");
options.put("isInitiator", "false");
{code}
I just removed this ticket cache related configuration.
