additional command at step 4, executing Hadoop
Hi,
I would like to contribute at the page:
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
I found a little improvement that might provide a better experience when
trying to execute the hadoop. This email serves to check with the
community if it is right.
On the topic "Pseudo-Distributed Operation", subtopic "Execution", step
4, an additional command should be executed after the other two:
$ bin/hdfs dfs -mkdir /user/friend/input
This is necessary because the command used in the step 5: the folder
"input" is not created automatically. So, it is necessary to create it.
Best regards,
Hylson

Hello Hylson,
Thank you for the offer to contribute a documentation improvement.
I'd expect this to work without explicitly running mkdir first. In fact,
creating the directory first yields a different final result. As written,
the instructions will produce /user/<username>/input/*. Changing it to
mkdir input explicitly first will produce /user/<username>/input/hadoop/*.
I just tested this against a current trunk build, and this is the behavior
that I saw.
In this particular case, it appears that we don't need to make a change.
However, for future contributions, please refer to this document:
http://wiki.apache.org/hadoop/HowToContribute
The source for the SingleCluster.html page is in the Hadoop source tree at
hadoop-common-project/hadoop-common/src/site/apt/SingleCluster.apt.vm. In
general, documentation sources will be in a src/site sub-directory under
the relevant sub-module.
