Subject [jira] [Commented] (HDFS-2941) Add an administrative command to download a copy of the fsimage from the NN
Date Sun, 12 Feb 2012 20:06:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13206503#comment-13206503
] 

Aaron T. Myers commented on HDFS-2941:
--------------------------------------

I'm envisioning something like `hdfs dfsadmin -fetchimage <local path>' which would
use the existing GetImageServlet to download the fsimage over HTTP, saving it at <local
path>.

purposes.
