It's mostly there, just needs a lock mechanism and a system test which should:

produce a batch of messages
run the job succesfully
produce another batch of messages
run the job and crash it after it has consumed some messages
re-run the job succesfully
check all messages from both batches are on hdfs exactly once

michal-harish added this to the 0.9 milestone
