master_0718_967cde6
RatisConsensus ,3 副本3C3D

先启动3C3D集群（ip3/4/5），扩容1个datanode（ip1）, 在ip5执行缩容ip3的操作。
ip3的datanode有error日志：
2022-07-18 14:00:00,830 [pool-16-IoTDB-Region-Migrate-Pool-1] ERROR o.a.i.d.s.RegionMigrateService$RegionMigrateTask:349 - add new peer TEndPoint(ip:192.168.130.1, port:40010) for region DataRegion[5] failed

缩容失败，可以连缩容datanode执行操作。
复现流程：
1. 启动3C3D 192.168.130.3/4/5  16C32G * 3

schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus

data_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
schema_replication_factor=3
data_replication_factor=3

MAX_HEAP_SIZE="16G"

2. 启动3个benchmark分别连3个datanode
benchmark在192.168.130.2
/home/benchmark/bm_0620_7ec96c1

配置文件见附件。

ip5执行缩容操作，缩容ip为192.168.130.3 ：
2022-07-18 *13:56:40*,902 [main] INFO  o.a.i.db.service.DataNode:201 - Remove result TDataNodeRemoveResp(status:TSStatus(code:200, message:Server accept the request)) 



3. iotdb的日志见附件
