> When a app starts, AMRMProxy.initializePipeline creates a new Interceptor
> chain and add it to its pipeline mapping. Then it initializes the chain and
> return. The problem is that when the chain initialization throws (e.g.
> because of configuration error, interceptor class not found etc.), the chain
> is not removed from AMRMProxy's pipeline mapping.
> This patch also contains misc log message fixes in AMRMProxy.
