Subject [jira] [Commented] (HDFS-2177) Restarting the namenode when the secondary namenode is checkpointing seems to remove everything from /
Date Wed, 20 Jul 2011 16:26:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13068474#comment-13068474

Arpit Gupta commented on HDFS-2177:
-----------------------------------

I believe the reason the restart of the namenode is necessary to see the issue as it re reads
the image file back in memory thus showing the users an empty namespace. However restart does
not play any role in making the edits log empty.
