Subject Re: additional command at step 4, executing Hadoop
Date Mon, 12 Jan 2015 18:02:49 GMT
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.
