Subject [jira] [Commented] (HDFS-9547) DiskBalancer : Add user documentation
Date Thu, 19 May 2016 20:16:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9547?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15292057#comment-15292057
] 

Arpit Agarwal commented on HDFS-9547:
-------------------------------------

This is excellent. A few nitpicky comments:
# The documentation should be under the hadoop-hdfs project.
# We should add a link to the DiskBalancer documentation from the HDFSCommands.html page.
Alternatively it can just be a sub-section in HDFSCommands.html like balancer, instead of
a new page.
# For commands the font is quite small. We could use the same font used by the HDFSCommands.html
page.
# Document verbose option for query
# The following statement could link to the balancer docs so the difference is clearer to
someone not familiar with the balancer. i.e. link to HDFSCommands.html#balancer

This tool is different from balancer which takes care of cluster-wide data balancing.
