Todd Lipcon commented on HDFS-2767:
-----------------------------------

{code}
+    } catch (RuntimeException rte) {
+      throw rte;
{code}
doesn't serve any purpose
----
- The functions createFailoverProxyWithNamenodeProtocol and 
createFailoverProxyWithClientProtocol are identical except for the class they 
take, right? Why not just make it take the interface class as a third parameter?
- Can you update NameNodeConnector.createNamenode to call 
createNNProxyWithNamenodeProtocol in this patch, just so we don't introduce new 
dup code here?

Thanks!

> Presentely ConfiguredFailoverProxyProvider supports ClinetProtocol.
> It should support NameNodeProtocol also, because Balancer uses 
> NameNodeProtocol for getting blocks.
