> Iteration on CredentialProviderFactory.serviceLoader is thread-unsafe

> Key: HADOOP-10829
> URL: https://issues.apache.org/jira/browse/HADOOP-10829
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.6.0
> Reporter: Benoy Antony
> Assignee: Benoy Antony
> Labels: BB2015-05-TBR
> Attachments: HADOOP-10829.patch, HADOOP-10829.patch

> CredentialProviderFactory uses _ServiceLoader_ framework to load
> _CredentialProviderFactory_
> {code}
> private static final ServiceLoader<CredentialProviderFactory> serviceLoader
> =
> ServiceLoader.load(CredentialProviderFactory.class);
> {code}
> The _ServiceLoader_ framework does lazy initialization of services which
> makes it thread unsafe. If accessed from multiple threads, it is better to
> synchronize the access.
> Similar synchronization has been done while loading compression codec
> providers via HADOOP-8406.
