Subject [jira] [Commented] (HDFS-7991) Allow users to skip checkpoint when stopping NameNode
Date Tue, 26 May 2015 20:34:23 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14559813#comment-14559813

Jing Zhao commented on HDFS-7991:
---------------------------------

We can use this jira just to remove the original dfsadmin scripts and add a script hook as
Allen did in his patch.

Allen, for your script patch, besides the "secretshutdownhook" is just a placeholder, looks
like you have not handled the HADOOP_OPTS issue right?

> This is a follow-up jira of HDFS-6353. HDFS-6353 adds the functionality to check if saving
namespace is necessary before stopping namenode. As [~kihwal] pointed out in this [comment|https://issues.apache.org/jira/browse/HDFS-6353?focusedCommentId=14380898&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14380898],
in a secured cluster this new functionality requires the user to be kinit'ed.
