### Why are the changes needed?

Fix: #2086

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

- Start multiply servers and coordinator on local
- Start a spark standalone env on local
- Start spark-shell and execute `test.scala`

```Console
bin/spark-shell  --master  spark://localhost:7077  --deploy-mode client --conf spark.rss.client.reassign.blockRetryMaxTimes=3 --conf spark.rss.writer.buffer.spill.size=30 --conf spark.rss.client.reassign.enabled=true  --conf spark.shuffle.manager=org.apache.spark.shuffle.RssShuffleManager --conf spark.rss.coordinator.quorum=localhost:19999  --conf spark.rss.storage.type=LOCALFILE --conf spark.serializer=org.apache.spark.serializer.KryoSerializer --conf spark.rss.test.mode.enable=true --conf spark.rss.client.type=GRPC_NETTY --conf spark.sql.shuffle.partitions=1  -i test.scala
```

- test.scala
```scala
val data = sc.parallelize(Seq(("A", 1), ("B", 2), ("C", 3), ("A", 4), ("B", 5), ("A", 6), ("A", 7),("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7), ("A", 7)));
val result = data.reduceByKey(_ + _);
result.collect().foreach(println);
System.exit(0);
