> 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
> Assignee: Joe McDonnell
> Priority: Critical
> Labels: broken-build, flaky
> Fix For: Impala 2.13.0, Impala 3.1.0
>
>
> 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.
