[jira] [Created] (HADOOP-12716) KerberosAuthenticator#doSpnegoSequence use incorrect class to determine isKeyTab in JDK8

Xiaoyu Yao created HADOOP-12716:
-----------------------------------

             Summary: KerberosAuthenticator#doSpnegoSequence use incorrect class to determine isKeyTab in JDK8
                 Key: HADOOP-12716
                 URL: https://issues.apache.org/jira/browse/HADOOP-12716
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao


HADOOP-11287 and HADOOP-10786 has fixed the issue in UserGroupInformation class for JDK8. 

However, the logic in KerberosAuthenticator#doSpnegoSequence is not updated. The KerberosKey.class below should be KeyTab.class for JDK8.

{code}
if (subject == null
          || (subject.getPrivateCredentials(KerberosKey.class).isEmpty()
              && subject.getPrivateCredentials(KerberosTicket.class).isEmpty())) {
{code}
