Authentication method compatible with MIT Kerberos
The Kerberos server in the EMR cluster is started at the master node on Alibaba Cloud E-MapReduce, I performed some management operations with the root account of the master node (emr-header-1).
I test accessing to HDFS service to introduce the relevant procedure as follows:
Executed hadoop fs -ls / on the Gateway
Use root account on the Gateway scp root@emr-header-1:/etc/krb5.conf /etc/
How can I add principal and export the keytab file using admin tool in Kerberos
I appreciate any assistance with this.
