I have setup a new HDP(3.1) cluster by enabling the kerberos. While running sample pi job it is failing with the error message. I have set the umask value to 022 in the shell before running the sample job. I have removed the appcache completely and rerun the job. But still the issue is there. If i disable kerberos then the job finishes successfully. Please let me know what could be the reason it will be very much helpful.
hadoop jar /usr/hdp/3.1.0.0-78/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 1 1

We wanted to implement 2FA with the Horton works cluster.( Secure token or Secure badge ). We have planned to configure Kerberos with AD integration. Does anybody have experience working with the multifactor authentication integration with hadoop. I couldn't find any documents related to the 2FA integration with the hadoop components.Does Hadoop framework supports MFA. Can somebody please help here. Thanks in Advance.
