/**
* A mechanism for selectively retrying methods that throw exceptions under
* certain circumstances.
* Typical usage is
* UnreliableImplementation unreliableImpl = new UnreliableImplementation();
* UnreliableInterface unreliable = (UnreliableInterface)
* RetryProxy.create(UnreliableInterface.class, unreliableImpl,
* RetryPolicies.retryUpToMaximumCountWithFixedSleep(4, 10,
* TimeUnit.SECONDS));
* unreliable.call();
*
* This will retry any method called on <code>unreliable</code> four times -
* in this case the <code>call()</code> method - sleeping 10 seconds between
* each retry. There are a number of
* {@link org.apache.hadoop.io.retry.RetryPolicies retry policies}
* available, or you can implement a custom one by implementing
* {@link org.apache.hadoop.io.retry.RetryPolicy}.
* It is also possible to specify retry policies on a
* {@link org.apache.hadoop.io.retry.RetryProxy#create(Class, Object, Map)
* per-method basis}.
