----------------------------------------

             Summary: RequestHedgingProxyProvider can hide Exception thrown from the Namenode
                 Key: HDFS-12813
                 URL: https://issues.apache.org/jira/browse/HDFS-12813
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: ha
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh


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.
