Subject [jira] [Commented] (HADOOP-8996) Error in Hadoop installation
Date Wed, 31 Oct 2012 15:37:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8996?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13487862#comment-13487862
] 

Robert Joseph Evans commented on HADOOP-8996:
---------------------------------------------

It is complaining that your input directory has a conf directory under it.  I am confused
about how

{code}
mkdir input
cp conf/*.xml input
{code}

could result in input/conf  My guess is that this is that you did something else with the
input directory that is not listed here.  If that is the case please correct it and try again.
 Also in general when you have problems with instillation etc it is a good idea to ask on
the user mailing list first before filing a JIRA to be sure that it is an actual bug int he
code or tutorial first.  If this turns out to be a bug in the tutorial feel free to reopen
this jira.
