--------------------------------
Summary: Replace the handwriting compare methods with static
compare methods in Java code
Key: SPARK-36047
URL: https://issues.apache.org/jira/browse/SPARK-36047
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.3.0
Reporter: Yang Jie
There are some handwriting compare methods like
`ShuffleInMemorySorter.SortComparator`
{code:java}
private static final class SortComparator implements
Comparator<PackedRecordPointer> {
@Override
public int compare(PackedRecordPointer left, PackedRecordPointer right) {
int leftId = left.getPartitionId();
int rightId = right.getPartitionId();
return Integer.compare(leftId, rightId);
}
}
{code}
the handwriting compare methods can replace with `Integer.compare()` method and
similar methods after Java 1.7
