Doug Cutting commented on HADOOP-1588:
--------------------------------------
Ideally we'd rethrow any exception that's:
a. compatible version loadable by the client JVM;
b. declared by the interface;
c. implements Writable (or perhaps Serializeable);
We'll never be able to rethrow all exceptions because of (a).
This was previously discussed in HADOOP-266.

> When an exception is thrown on the server side, the Hadoop IPC bundles it up

> If the original exception was a subclass of IOException or RuntimeException,
> HClient should unwrap the RemoteException and throw the original exception
