-------------------------------------
Summary: Renaming table will cause losing privileges for non-admin
users
Key: IMPALA-12190
URL: https://issues.apache.org/jira/browse/IMPALA-12190
Project: IMPALA
Issue Type: Bug
Components: Catalog
Reporter: Gabor Kaszab
Let's say user 'a' gets some privileges on table 't'. When this table gets
renamed (even by user 'a') then user 'a' loses its privileges on that table.
Repro steps:
# Start impala with Ranger
# start impala-shell as admin (-u admin)
# create table tmp (i int, s string) stored as parquet;
# grant all on table tmp to user <username>;
# grant all on table tmp to user <username>;
{code:java}
Query: show grant user <username> on table tmp
