plz find attached log file for further reference.traceback-log.txt

After finished deployment & installation of Kerberos, while editing the parameters "hadoop.security.authentication" & "hadoop.security.authorization" in core-site.xml file, all the mentioned services failed to start with the given logs.

It is not going to start after the kerberos implementation.

plz look into the same & do the needful if possible.

@hardik desai Could you please confirm if both your name nodes are up and running as expected after enabling kerberos? Please check if Ambari is able to recognize and display active/standby state of your name nodes(If NN HA configured).

@Vaisakh Sundaram thanks for your reply. We have not configured namenode HA here.

Services like HDFS, YARN,MR failed to start after enabling kerberos.

@hardik desai

Could you please paste the exception you are getting on HDFS /YARN logs at the time of starting the services? What is the value configured for the properties "hadoop.security.authentication" & "hadoop.security.authorization"?
