I've got HDP3 kerberized cluster.
The question is - how can I create delegation token for user that doesn't have keytab?
With that user I want to retrieve information from Metastore and run SQL queries on Hive tables.
Property hive.cluster.delegation.token.store.class equals to org.apache.hadoop.hive.thrift.ZooKeeperTokenStore
Znodes /hive/cluster/delegationHIVESERVER2/tokens and /hive/cluster/delegationMETASTORE/tokens are empty.
I've found information about how to generate DT for HDFS.
But for Hive there is info only about how to get that token, it means, that the token already exists. But how to create one?
