Prerequisites for running backup and restore operations for a NetBackup for Hadoop cluster with Kerberos authentication
To run backup and restore operations for a NetBackup for Hadoop cluster that uses Kerberos authentication, NetBackup for Hadoop needs a valid Kerberos ticket granting-ticket (TGT) to authenticate with the NetBackup for Hadoop cluster.
Note:
During the backup and restore operations, the TGT must be valid. Thus, specify the TGT validity accordingly or renew it when required during the operation.
Run the following command to generate the TGT:
kinit -k -t /keytab_file_location/keytab_filename principal_name
For example,
kinit -k -t /usr/openv/var/global/nbusers/hdfs_mykeytabfile.keytab hdfs@MYCOMPANY.COM
Also review the configuration-related information. See Configuration for a NetBackup for Hadoop cluster that uses Kerberos.
