---------------------------------

             Summary: RocksIteratorWrapper.seekToLast() calls the wrong 
RocksIterator method
                 Key: FLINK-24432
                 URL: https://issues.apache.org/jira/browse/FLINK-24432
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends
    Affects Versions: 1.14.0
            Reporter: Victor Xu


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.
{code:java}
@Override
public void seekToFirst() {
 iterator.seekToFirst();
 status();
}

@Override
public void seekToLast() {
 iterator.seekToFirst();
 status();
}{code}
