Íñigo Goiri updated HDFS-13976:
-------------------------------
Description:
2.9 also shows the issue from HDFS-12813:
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.
> Backport HDFS-12813 to branch-2.9
