> When (BlockOpResponseProto#getStatus() != SUCCESS), it helps with debugging if DFSClient
can add BlockOpResponseProto's message to the exception message applications will get. For
example, instead of
> {noformat}
>         throw new IOException("Got error for OP_READ_BLOCK, self="
>             + peer.getLocalAddressString() + ", remote="
>             + peer.getRemoteAddressString() + ", for file " + file
>             + ", for pool " + block.getBlockPoolId() + " block " 
>             + block.getBlockId() + "_" + block.getGenerationStamp());
> {noformat}
> It could be,
> {noformat}
>         throw new IOException("Got error for OP_READ_BLOCK, self="
>             + peer.getLocalAddressString() + ", remote="
>             + peer.getRemoteAddressString() + ", for file " + file
>             + ", for pool " + block.getBlockPoolId() + " block " 
>             + block.getBlockId() + "_" + block.getGenerationStamp()
>             + ", status message " + status.getMessage());
> {noformat}
> We might want to check out all the references to BlockOpResponseProto in DFSClient.
