YCSB 基准测试期间的 Hbase [READ-FAILED]

Hbase [READ-FAILED] during YCSB Benchmarking

我正在使用 CDH 并通过安装的 HBase 和下载的 YCSB Package.Now 而 运行 使用以下命令在 Hbase 上进行测试:

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

它给出的输出如下,其中近 50% 的读取失败:

我尝试在数据库创建期间更改 split_no,还读取复制因子也已启用并在 table 创建期间设为 3。

我正在寻找发生这种情况的原因,但没有成功,有人可以帮助我完成这项工作吗??

我在运行 YCSB 时遇到了同样的问题。我仍然没有解决这个问题,但也许这对你的情况有帮助:

这家伙通过将工作负载文件中的 field_length 值从 255 降低到 250 解决了这个问题。
