Authorization errors in Impala

Authorization errors in Impala

Rising Star



We have a strange issue here.


We are on CDH 6.3.0 and have sentry in place for authorizations. A user is trying to execute queries from Hue on Impala Editor and fails with Authorization errors. However, same query works fine via Hive and also via Impala shell. It fails only from Hue editor.


We have:

1. Refreshed metadata

2. Invalidated metadata

3. Verified permissions are in place in Sentry

4. There are no logs generated (I checked in Hue, Sentry Server and Catalog server). Please suggest if any other place should also be checked.


Example query:

select * from DB.table limit 5;


Kindly help to diagnose and resolve this issue.
