java.lang.Object
- org.apache.hadoop.hbase.regionserver.KeyValueHeap.KVScannerComparator
- - org.apache.hadoop.hbase.regionserver.ReversedKeyValueHeap.ReversedKVScannerComparator

All Implemented Interfaces:

Comparator<KeyValueScanner>

Enclosing class:

ReversedKeyValueHeap
```
private static class ReversedKeyValueHeap.ReversedKVScannerComparator
extends KeyValueHeap.KVScannerComparator
```
In ReversedKVScannerComparator, we compare the row of scanners' peek values first, sort bigger one before the smaller one. Then compare the KeyValue if they have the equal row, sort smaller one before the bigger one
