Subject [jira] [Commented] (HDFS-7991) Allow users to skip checkpoint when stopping NameNode
Date Mon, 30 Mar 2015 21:12:52 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14387419#comment-14387419
] 

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

bq. b) Why are we trying to fix this at the shell level instead of at the Java level?

This has been answered in [here | https://issues.apache.org/jira/browse/HDFS-8003?focusedCommentId=14387349&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14387349]
and [here | https://issues.apache.org/jira/browse/HDFS-8003?focusedCommentId=14384256&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14384256].
From your comment in HDFS-8003, I still did not see a valid point against doing this in the
shell script.

bq. d) There's no way this passes shellcheck.

At least it passes the shellcheck in my local machine. Can you post the warning msg you see?

bq. -1

Just to clarify, is this -1 on the feature itself or just mean you want me to address your
comments? If it's the later I will try to address your comments in the next patch.

> 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.
