> TestHadoop20SAuthBridge tests fail sometimes because of race condition
> ----------------------------------------------------------------------
>
> Key: HIVE-4883
> URL: https://issues.apache.org/jira/browse/HIVE-4883
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Tests
> Affects Versions: 0.11.0
> Reporter: Thejas M Nair
> Assignee: Thejas M Nair
>
> TestHadoop20SAuthBridge tests testSaslWithHiveMetaStore and
> testMetastoreProxyUser sometimes fail. I have seen this more often on mac and
> windows, but this can happen on linux as well.
> The problem is that metastore is started in a different thread and these unit
> tests actually rely on the metastore having initialized
> DelegationTokenSecretManager in HadoopThriftAuthBridge20S as part of the
> metastore startup (HiveMetaStore.startMetaStore )
