victorunique opened a new pull request #17475:
URL: https://github.com/apache/flink/pull/17475
## What is the purpose of the change
The RocksIteratorWrapper is a wrapper of RocksIterator to do additional
status check for all the methods. However, there's a typo that
RocksIteratorWrapper.seekToLast() method calls RocksIterator's seekToFirst(),
which is obviously wrong. I guess this issue wasn't found before as it was only
referenced in the RocksTransformingIteratorWrapper.seekToLast() method and
nowhere else.
## Brief change log
- *Replace the iterator.seekToFirst() to the iterator.seekToLast() in the
seekToLast method;*
