------------------------------------
Summary: Confusing error messages in PrivilegeSpec
Key: IMPALA-8649
URL: https://issues.apache.org/jira/browse/IMPALA-8649
Project: IMPALA
Issue Type: Sub-task
Components: Frontend
Affects Versions: Impala 3.2.0
Reporter: Fredy Wijaya
Some error messages in PrivilegeSpec are confusing. For example:
https://github.com/apache/impala/blob/d753600f9cf4bda0c955f0f5eecc6fb41b0c365e/fe/src/main/java/org/apache/impala/analysis/PrivilegeSpec.java#L204-L206
https://github.com/apache/impala/blob/d753600f9cf4bda0c955f0f5eecc6fb41b0c365e/fe/src/main/java/org/apache/impala/analysis/PrivilegeSpec.java#L254-L258
https://github.com/apache/impala/blob/d753600f9cf4bda0c955f0f5eecc6fb41b0c365e/fe/src/main/java/org/apache/impala/analysis/PrivilegeSpec.java#L287-L289
We should still aim to not reveal the existence of an object, however the
message "Error setting privileges" and "Verify that you have permissions to
issue GRANT/REVOKE statement" can be misleading since PrivilegeSpec is also
used for "SHOW GRANT", which doesn't set any privileges.
