Subject [jira] [Commented] (HDFS-2580) NameNode#main(...) can make use of GenericOptionsParser.
Date Mon, 02 Jul 2012 02:34:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404878#comment-13404878

Harsh J commented on HDFS-2580:

Yes I wished to avoid editing conf files when bringing up NNs locally for testing with some
tweaked params. The use-case I had was to start NN via "hadoop namenode -Dopts=values". Most
of the daemons have a GOP (if not Tool, which is fine too), except for NameNode.

The -fs helps set the port.

> DataNode supports passing generic opts when calling via {{hdfs datanode}}. NameNode can
support the same thing as well, but doesn't right now.
