             Summary: TestTPCHJoinQueries.test_outer_joins create duplicate 
table
                 Key: IMPALA-13343
                 URL: https://issues.apache.org/jira/browse/IMPALA-13343
             Project: IMPALA
          Issue Type: Bug
          Components: Test
            Reporter: Riza Suminto
            Assignee: Riza Suminto


TestTPCHJoinQueries.test_outer_joins run tpch-outer-joins.test, which have 
following drop/create table query.
{code:java}
drop table if exists default.t1;
drop table if exists default.t2;
create table default.t1(`insert` bigint);
create table default.t2(`select` bigint); {code}
If two test_outer_joins with different test vector run concurrently, one of 
them can hit AnalysisException as follows:
{code:java}

    self.run_test_case('tpch-outer-joins', vector)

    raise ImpalaBeeswaxException(self.__build_error_message(b), b)
E   ImpalaBeeswaxException: Query 65446c2aeefc64b1:f305c36400000000 failed:
E   AnalysisException: Table already exists: default.t1 {code}
Both t1 and t2 table in test case should be created using unique database.
