I am running Cloudera 5.15, with Kerboros enabled on the cluster. Sentry is installed to configure user access to various tables/databases ...etc.
Everything is installed and working fine for Hive, but not for Impala.
I'm using Hue web UI for issuing hive/impala queries. (I'm getting same results using beeline and impala-shell though)
From Hue/Hive:
show current roles;
return --> "professors_role"
From Hue/Impala
show current roles;
return --> no results
When I issue "select current_user()" from hive and impala query editors I'm getting different results.
From hive "select current_user()" returns "hive"
from impala "select current_user()" returns "professor1"
I'm thinking perhaps this is the kulprit, but i'm not sure how to fix? Maybe I've missed a configuration setting in impala somewhere?
Everything works fine in hive - logging in as different users shows me different databases and tables as I would expect based on their assigned roles. Users logged into Impala can't see anything.
Any help is greatly appreciated.
Thanks
I've had this problem, but I fix it now. You can check which machine you install the impala statestore, and you must have the same impala user/group on the linux system.
