--------------------------------------------
Summary: LLAP: Login with kerberos before starting the daemon
Key: HIVE-15403
URL: https://issues.apache.org/jira/browse/HIVE-15403
Project: Hive
Issue Type: Bug
Components: llap
Affects Versions: 2.2.0
Reporter: Prasanth Jayachandran
Assignee: Prasanth Jayachandran
Priority: Critical
In LLAP cluster, if some of the nodes are kinit'ed with some user (other than
default hive user) and some nodes are kinit'ed with hive user, both will end up
in different paths under zk registry and may not be reported by the llap status
tool. The reason for that is when creating zk paths we use UGI.getCurrentUser()
but current user may not be same across all nodes (someone has to do global
kinit). Before bringing up the daemon, if security is enabled each daemons
should login based on specified kerberos principal and keytab for llap daemon
service and update the current logged in user.
