Botong Huang updated YARN-6281:
-------------------------------
Description:
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.
