> Teragen with Ozone is reported to be slower with Ozone than Hdfs with some specific configuration.
> To make it easier to compare different file system, we need an easy measurement on the same point (FSDataOutputStream.write) to compare the time spent in that method with Hdfs/Ozone/other file systems.
> It can be done with a byteman instrumentation rule
