   That I am not sure of. @keith-turner or @EdColeman might be able to answer 
that. IIRC the Deriver functionality is new in 2.1 with the re-write of the 
configuration implementation.

   I assume that you have set the replication on the HDFS classpath artifacts 
sufficiently high. Have you tried other mechanisms that VFS supports (e.g. 
http) for distributing the jars?

   I think the VFS classloader should retry. Presumably the VFS classloader is 
getting an exception from HDFS, so it should retry in that case. If we were to 
do something in Accumulo, then we would have to do it in a lot of places. 
Additionally, the contract for a ClassLoader is that you call it once and you 
either get a Class or an Exception.
