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??

我的ycsb跑步也有同样的表现。我仍然没有解决这个问题,但这可能对您的案例有所帮助:

他通过将工作负载文件中的字段长度值从255降低到250来解决这个问题。
