Joe McDonnell created IMPALA-7238:
-------------------------------------
Summary: test_kudu.TestCreateExternalTable sees unique database
already exists
Key: IMPALA-7238
URL: https://issues.apache.org/jira/browse/IMPALA-7238
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 3.1.0
Reporter: Joe McDonnell
All of the tests from query_test.test_kudu.TestCreateExternalTable fail with an
error like:
{noformat}
/data/jenkins/workspace/impala-asf-master-core-s3/repos/Impala/infra/python/env/lib/python2.7/site-packages/impala/hiveserver2.py:704:
in err_if_rpc_not_ok
raise HiveServer2Error(resp.status.errorMessage)
E HiveServer2Error: ImpalaRuntimeException: Error making 'createDatabase' RPC
to Hive Metastore:
E CAUSED BY: AlreadyExistsException: Database
testcreateexternaltable_23808_vu8cqo already exists{noformat}
It looks like the failures all happen at once in a single process. The first
test to fail is test_kudu.TestCreateExternalTable.test_col_types. It takes 52
seconds where all the other tests take no time. It also has an extra error on
stderr:
{noformat}
-- connecting to: localhost:21000

The other failures don't have this.
This happened only once, so it is definitely intermittent. This has some
similarity to IMPALA-6933, but this looks like a repeated failure in a single
process, not a concurrency issue.
