Vinayakumar B commented on HDFS-9503:
-------------------------------------
Since {{NNThroughputBenchmark}} is an implementation of {{Tool}} interface,
which already supports parsing of {{-fs}} option as part of GenericOptions
provided these are mentioned at first.
I think, Since {{-fs}} is already provided by default, Now just need another
flag ( may be instead of -namenode) to mention whether to use New Namenode
instance, or just connect to remote namenode.
Also, this would be an Incompatible change,
> Replace -namenode option with -fs for NNThroughputBenchmark

> HDFS-7847 introduced a new option {{-namenode}}, which is intended to point
> the benchmark to a remote NameNode. It should use a standard generic option
> {{-fs}} instead, which is routinely used to specify NameNode URI in shell
> commands.
