Subject [jira] [Commented] (HDFS-1704) Federation: Add a tool that lists namenodes, secondary and backup nodes from the configuration file
Date Mon, 21 Mar 2011 03:45:54 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1704?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009011#comment-13009011

Suresh Srinivas commented on HDFS-1704:
---------------------------------------

readability in usage it is printed in camelCase. Perhaps we should have some coding convention
around this.
