Rui Li commented on HDFS-8968:
------------------------------
[~andrew.wang] - It's good idea to put it in hadoop-tools. Problem is that I
don't see any appropriate existing module where the tool fits in (the tool
benchmarks throughput of read/write files for both EC and replica mode). Does
it make sense to create a new module, say hadoop-benchmark, under hadoop-tools?
Other upcoming benchmark tools can also be put there, e.g. HADOOP-11588, which
benchmarks performance of different EC codecs.
As to unit test, maybe I can add a test where the tool runs against a
MiniDFSCluster. Sounds good?

> 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.
