Subject [jira] [Commented] (HADOOP-12498) Correct CL commands for the Pseudo-Distributed Operation setup
Date Wed, 21 Oct 2015 15:14:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14967291#comment-14967291
] 

Allen Wittenauer commented on HADOOP-12498:
-------------------------------------------

bq.  but the folder is only "input", instead it should be "/user/<username>/input".

{code}
  $ bin/hdfs dfs -put etc/hadoop input
{code}

is the same thing as

{code}
$ bin/hdfs dfs -put etc/hadoop /user/<username>/input
{code}

So unless the example requires input to be a directory, these are equivalent statements. 
I do think the documentation should be cleaned up to point out absolute vs. relative paths
here though.

The other thing is that this should really be using 'hadoop fs' instead of 'hdfs dfs' so that
it works on non-HDFS-based file systems.

>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: site
>    Affects Versions: 2.7.1

> The Setup [Guide|https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html#Fully-Distributed_Operation]
for Hadoop 2.7.1 to run in Pseudo-Distributed Operation mode has inconsistent CL commands
.
> In step 4., a directory is created ("/user/<username>") in which all further files
are going to be stored.
> Step 5 is used to put files into the hdfs, but the folder is only "input", instead it
should be "/user/<username>/input".
> The same applies for step 6 and 7.
