Pre-requisite for running backup and restore operations for a HBase cluster with Kerberos authentication

To run backup and restore operations for a HBase cluster that uses Kerberos authentication, HBase needs a valid Kerberos ticket granting-ticket (TGT) to authenticate with the HBase 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/netbackup/nbusers/hbase_mykeytabfile.keytab hbase@MYCOMPANY.COM

Also review the configuration-related information. See Configuration for a HBase cluster that uses Kerberos.
