-------------------------------------
Summary: Iteration on KeyProviderFactory.serviceLoader is
thread-unsafe
Key: HADOOP-10826
URL: https://issues.apache.org/jira/browse/HADOOP-10826
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: Benoy Antony
Assignee: Benoy Antony
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.
