Aaron T. Myers commented on HADOOP-7931:
----------------------------------------

I tested this patch by applying this with the patch posted on HDFS-2694 and confirmed manually that the NN protocols which still use WritableRpcEngine work again with these patches.

> {{WritableRpcEngine}} currently relies on a static initializer to register itself with {{o.a.h.ipc.Server}} as a valid {{RpcKind}}. There should be a way to ensure this initialization has already occurred.
