Kai Zheng commented on HDFS-8968:
---------------------------------
Yes the purpose for this new tool is to benchmark throughput of HDFS client
read and write, for both replica and striping modes, considering we may make
the tool more erasure coding specific in future, I thought it's OK not to use a
general name. Then, better to use {{ErasureCodingBenchmarkThroughput}} for
consistency.

> Project: Hadoop HDFS
> Issue Type: Sub-task

>
> We need a new benchmark tool to measure the throughput of client writing and
> reading considering cases or factors:
> * 3-replica or striping;
> * write or read, stateful read or positional read;
> * which erasure coder;
> * striping cell size;
> * concurrent readers/writers using processes or threads.
> The tool should be easy to use and better to avoid unnecessary local
> environment impact, like local disk.
