--------------------------------------------
Summary: GenericUDTFGetSplits should handle usernames in the same
way as LLAP
Key: HIVE-21913
URL: https://issues.apache.org/jira/browse/HIVE-21913
Project: Hive
Issue Type: Bug
Affects Versions: 4.0.0, 3.2.0
Reporter: Prasanth Jayachandran
Assignee: Prasanth Jayachandran
LLAP ZK registry namespacing includes current user name which is typically
hive. But in some deployments, usernames are created with '_' like hive_dev.
RegistryUtils.currentUser() (that LLAP uses) replaces '_' with '-' for DNS
reasons. But GenericUDTFSplits uses UGI login user which does not do the
underscore replacement. As a result, LlapBaseInputFormat is finding any LLAP
daemons even though they are running.
