Steve Loughran commented on HADOOP-14200:
-----------------------------------------
the test logs probably have more detail,
1. The inner socket stuff isn't being translated
2. the rethrown message doesn't include the error of the inner exception in its
text
The combination means that the root cause is being lost, and even that lacks
diagnostics information
