Description

The code comments for SubtaskStateMapper.RANGE are as follows:

 * <p>Example:<br>
 * old assignment: 0 -> [0;43); 1 -> [43;87); 2 -> [87;128)<br>
 * new assignment: 0 -> [0;64]; 1 -> [64;128)<br>
 * subtask 0 recovers data from old subtask 0 + 1 and subtask 1 recovers data from old subtask 0
 * + 2

The correct code comment should be：

 

 * <p>Example:<br>
 * old assignment: 0 -> [0;43); 1 -> [43;87); 2 -> [87;128)<br>
 * new assignment: 0 -> [0;64]; 1 -> [64;128)<br>
 * subtask 0 recovers data from old subtask 0 + 1 and subtask 1 recovers data from old subtask 1
 * + 2

subtask 1 should recovers data from old subtask 1 + 2，not from old subtask 0 + 2
