chao commented on KAFKA-4844:
-----------------------------

we want to delete index and log files under  TOPIC_PARTITION_X/... and  
__consumer_offsets-/...  7 days ago 
how can we configure that ?? what is the detail mean for log.cleaner.enable and 
offsets.retention.minutes??
for example :
offsets.retention.minutes=10080

> kafka is holding open file descriptors
