我正在使用cdh，并通过该内置hbase下载了ycsb包。现在使用以下命令在hbase上运行测试：

ycsb run hbase10 -p columnfamily=cf -P /usr/share/ycsb/workloads/workloada -s -threads 100 -p  recordcount=5000 -p operationcount=5000

其输出如下，其中大约50%的读取失败：

我尝试在数据库创建期间更改split\ u no，在表创建期间还启用了read replication factor并设置为3。
我正在寻找为什么会这样，但运气不好，有人能帮我做这件事吗？？
