Hi guys:
we have used kafka-0.8.1 under three machines (broker 0,broker 1,broker 3).
After running several months, some partions is out of sync; how to recover from
this situation ?

Here is the related log in borker 0
state-change.log
./state-change.log.2015-08-01:[2015-08-01 06:01:51,449] WARN Broker 0 received

with an older leader epoch 0 for partition [analyze,0], current leader epoch is

controller.log

Thanks and regards
