Ok, thanks for the JIRA ticker. I've found that very same problem
during my work on ignoring unavailabla ranges.

But there is the another problem with Hadoop-Cassandra, if there is no
node available for a range of keys, it fails on RuntimeError. For
example having a keyspace with RF=1 and a node is down all MapReduce
tasks fail. I've reworked my previous patch, that was addressing this
issue and now there are ConfigHelper methods for enable/disable
ignoring unavailable ranges.
It's available here: http://pastebin.com/hhrr8m9P (for version 0.7.8)
I hope it can be applied.

Regards,
Patrik
