I just merged this to branch-1.1 after Matt's go ahead.

Matt - if you don't mind, I'd like to merge this into branch-1.1 since it's a trivial change. Thoughts?

I just committed the branch-1 patch too.

Thanks for the review Nic, added the toString() method.

+1 for the branch-1 patch once the toString() method has been added.

I have committed the trunk patch. Thanks, Arun!

For the branch-1 patch, the toString() method is missing.

//DFSClient.java line 179
        @Override
        public String toString() {
          return "RetryPolicy[" + multipleLinearRandomRetry + ", "
              + RetryPolicies.TRY_ONCE_THEN_FAIL.getClass().getSimpleName()
              + "]";
        }

Fixed trunk patch.

Trunk patch needs work to handle ServiceException.

Trivial patch for trunk.

Trivial patch for branch-1.
