> KeyProviderFactory uses _ServiceLoader_ framework to load _KeyProviderFactory_
> {code}
> private static final ServiceLoader<KeyProviderFactory> serviceLoader =
> ServiceLoader.load(KeyProviderFactory.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.
