Subject [jira] [Commented] (HDFS-4533) start-dfs.sh ignored additional parameters besides -upgrade
Date Fri, 10 May 2013 18:25:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13654691#comment-13654691
] 

Colin Patrick McCabe commented on HDFS-4533:
--------------------------------------------

I ran the command with the patch, and {{./sbin/start-dfs.sh -crazygonuts}} was rejected. 
However, {{./sbin/start-dfs.sh -upgrade -crazygonuts}} was accepted without a visible error
message.

Given that the obvious error handling cases are covered, I withdraw my earlier objection.
 I still think we should add a way to pass arguments to the other daemons, but I suppose that
can be added in a separate JIRA when we actually need it.

> start-dfs.sh only takes -upgrade option and ignored others. 
> So If run the following command, it will ignore the clusterId option.
> start-dfs.sh -upgrade -clusterId 1234
