             Summary: Iteration on KeyProviderFactory.serviceLoader  is thread-unsafe
                 Key: HADOOP-10827
                 URL: https://issues.apache.org/jira/browse/HADOOP-10827
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Benoy Antony
            Assignee: Benoy Antony

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