Subject [jira] [Commented] (HADOOP-7955) hadoop 1.0.0 debian installer : hadoop-setup-conf.sh fails on chownsc
Date Wed, 04 Jan 2012 18:57:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7955?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179748#comment-13179748
] 

Arpit Gupta commented on HADOOP-7955:
-------------------------------------

we should change the default mapred user to 'mapred' instead of 'mr' in these scripts. Also
did you run these scripts as user root? 

The various setup scripts need to be executed by user root.
