      Description

      • Presently when jobs are run in the Hadoop ecosystem, the implicit assumption is that YARN will be used as a scheduling agent with access to appropriate keytabs for renewal of kerberos tickets and delegation tokens.
      • Jobs that interact with kerberized hadoop services such as hbase/hive/hdfs and use an external scheduler such as Kubernetes, typically do not have access to keytabs. In such cases, delegation tokens are a logical choice for interacting with a kerberized cluster. These tokens are issued based on some external auth mechanism (such as Kube LDAP authentication).
