-----------------------------------
Summary: CSV output support for NNThroughputBenchmark
Key: HDFS-17039
URL: https://issues.apache.org/jira/browse/HDFS-17039
Project: Hadoop HDFS
Issue Type: Improvement
Components: benchmarks, test
Reporter: Mark Bukhner
Now the NNThroughputBenchmark has only console result output, i use this
benchmark a lot and it's more convenient to have ability to write benchmark
results in csv file.
This change add BenchmarkOutputWriter class, which prints any benchmark results
in csv file, this entity could work with any benchmark. To implement this
feature in benchmark, @Parameter annotation was added in benchmark fields.
I think this option very helpful for community
