EMsnap opened a new pull request, #7856:
URL: https://github.com/apache/inlong/pull/7856
### Prepare a Pull Request
- Fixes #7855
### Motivation
Fix Sort hang up reader in snapshot phase when reducing parallelism
1、When a subtask receives two chunk splits to read;
2、The first chunk reads perfectly, and then it will start a BinlogClient to
read the binlogs from lw to hw in chunk1.
3、When the second chunk arrives the BinlogClient will be reused
4、So when reading chunk2 and start to read from lw to hw in chunk2, the
binlog reader will be reused and the event listener in chunk1 will be reused
also. So that the BINLOG_END event in chunk2 will never be received
### Modifications
remove the eventListener in the formal chunk
