Chris Nauroth commented on HADOOP-13452:
----------------------------------------

[~fabbri], thank you for this patch.  I have just one minor nitpick.

{code}
    return (fStr.indexOf(aStr) == 0);
{code}

I think this line would be more readable using [{{String#startsWith(String)}}|http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#startsWith(java.lang.String)].

After that change, I think I'll be ready to commit the patch to the feature branch.

> Implement an S3A access policy based on an in-memory metadata store.  This can provide consistency within the same client without needing to integrate with an external system.
