> Key: HDFS-17272
> URL: https://issues.apache.org/jira/browse/HDFS-17272
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.4.0
> Reporter: caozhiqiang
> Assignee: caozhiqiang
> Priority: Major
> Labels: pull-request-available
>
> Currently, NNThroughputBenchmark does not support specifying the base
> directory, therefore does not support multiple clients performing stress
> testing at the same time. However, for high-performance namenode machine,
> only one client submitting stress test can not make the namenode rpc access
> reach the bottleneck. Therefore, multiple clients are required for parallel
> testing to make the namenode pressure reach the level of the large-scale
> production cluster.
> So I specify the base directory through the -baseDirName parameter to support
> multiple clients submitting stress tests at the same time.
