User Impersonation for Hive
User impersonation enables Hive to submit jobs as a particular user. Without impersonation,
Hive submits queries and hadoop commands as the user that started HiveServer2 and Hive
Metastore. On a Data Fabric cluster, this user is typically
the mapr
user or the user specified in the MAPR_USER
environment variable.
NOTE
Impersonation is enabled by default.
