Konstantin Shvachko updated HADOOP-3860:
----------------------------------------
Attachment: NNThruputMoreOps.patch
I am attaching a patch that was used for the benchmarks.
It extends {{NNThroughputBenchmark}} with new operations {{rename}} and
{{delete}} as well as introduces additional command line options,
which control what the benchmarks do with generated files before and after the
execution.
> Compare name-node performance when journaling is performed into local
> hard-drives or nfs.
