>             Fix For: 0.18.0
> Rather than tracking the total number of times DFSInputStream failed to locate a datanode
for a particular block, such failures and the the list of datanodes involved should be scoped
to individual blocks. In particular, the "deadnode" list should be a map of blocks to a list
of failed nodes, the latter reset and the nodes retried per the existing semantics.
