> 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.
