litao91 opened a new issue #7949: KIS: potential data overriding when taskDuration is set
URL: https://github.com/apache/incubator-druid/issues/7949
 
 
   ### Affected Version
   
   Since KIS is introduced 
   
   ### Description
   
   Consider the following case
   
   1. We have a KIS generates a segment of 12:00-13:00, of version v1
   2. At 12:30 the all the sub tasks come to the end of duration and release the locks at nearly the same time. 
   3. New subtasks start and create new segment, also of interval 12:00-13:00. Since we have to acquire new lock for new tasks, the segment have new version of v2
   4. Then, the same interval of v2 will overshadow that of v1, which is unexpected.
