YCSB无法将数据加载到cassandra多节点

我正在尝试使用YCSB工具将数据加载到cassandra multinode设置中，使用下面的命令

./ycsb  load cassandra-10 -P ../workloads/workloadb -s 

但我得到了以下输出。
我将hosts参数作为服务器的IP地址放在工作负载中

另外，我能够成功创建多节点设置，并使用表“数据”创建db“usertable”

您需要将所有种子节点的IP地址放在您在yaml文件中提供的主机参数中。

最后得到这个错误。org.apache.cassandra.thrift.cassandra$batch_mutate_result.read（cassandra.java:16485）org.apache.cassandra.thrift.cassandra$Client.recv_batch_mutate（cassandra.java:916）org.apache.cassandra.thrift.cassandra$Client.batch_mutate（cassandra.java:890）com.yahoo.ycsb.db.cassandract10.insertcom.yahoo.ycsb.DBWrapper.insert（DBWrapper.java:148）com.yahoo.ycsb.workloads.corewloads.doInsert（corewloads.java:461）com.yahoo.ycsb.ClientThread.run（Client.java:277）
