----------------------------------
Summary: NNThroughputBenchmark should support specifying the base
directory for multi-client test
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
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.
