Subject [jira] [Commented] (HDFS-9503) Replace -namenode option with -fs for NNThroughputBenchmark
Date Mon, 25 Jan 2016 11:14:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9503?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15115050#comment-15115050
] 

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,

> 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.
