   > The unseq merge selector try to filter unseq files which overlapped with some open file. However, the open file's endTime is always Long.MIN_VALUE which will be filtered in pervious logic. So unseq files which overlapped with some open file cannot be excluded.
   
   ## Behavior
   
   ...
   
   ## Reasom
   
   The unseq merge selector tries to find unseq files which overlap with some unsealed files. 
   
   However, the unsealed file's endTime is always Long.MIN_VALUE which will be ignored because [Long.MIN_VALUE, Long.MIN_VALUE) never overlap with other files . 
   
   As a result,  the unseq files which overlapped with some unsealed file cannot be excluded. (what is this meaning????)
   
   ## Solution
   
   .....
