> HDFS-11395 fixed the problem where the MultiException thrown by RequestHedgingProxyProvider was hidden. However when the target proxy size is 1, then unwrapping is not done for the InvocationTargetException. for target proxy size of 1, the unwrapping should be done till first level where as for multiple proxy size, it should be done at 2 levels.
