             Summary: [rel/1.0] Internal error processing createSchemaRegion : 
NPE
                 Key: IOTDB-5073
                 URL: https://issues.apache.org/jira/browse/IOTDB-5073
             Project: Apache IoTDB
          Issue Type: Bug
          Components: mpp-cluster
    Affects Versions: 1.0.0
            Reporter: 刘珍

测试描述：
启动3C3D1BM，间隔10分钟，执行1次扩容3DataNode，增加1BM；最终3C21D7BM。
BM配置(所有BM往1db里写）
读写混合：OPERATION_PROPORTION=70:1:1:1:1:0:1:1:1:1:1
DEVICE_NUMBER=2000
SENSOR_NUMBER=1000
CLIENT_NUMBER=50
DEVICE_NAME_PREFIX=d[${idx}]_
