The most newbie question ever
After three years in a non-Hadoop Windows wilderness I am lucky enough to
return and wow I find Hadoop 2.0 .... Brilliant!
I quickly navigated here:
http://hadoop.apache.org/index.html#Getting+Started
and eagerly downloaded 2.0.3 alpha. Hmmm, now what? I see the following
sections,
*Getting Started *
*To get started, begin here:*
1. *Learn about <http://hadoop.apache.org/docs/current/> Hadoop by
reading the documentation.*
2. *Download <http://hadoop.apache.org/releases.html> Hadoop from the
release page.*
3. *Discuss <http://hadoop.apache.org/mailing_lists.html> Hadoop on the
mailing list.*
but I can't find installation instructions. I look for the latest version
of my Tom White collection and the latest book is a year old and is
unlikely to be current enough to be of use to someone as out of date as me.
Please help me to get started. So far I've only managed to download and
unzip 2.0.3 and to install open jdk 6.
Many thanks for your patience.

OK. I have kept battling through, guessing at the gaps in the getting
started page but the final command to run the hadoop-examples.jar has
blocked me. As far as I can tell there is no hadoop-examples.jar file in
the distribution.
At a higher level I must be doing something wrong. The path I've
*followed*makes it seem as if there are effectively zero getting
started docs. This
cannot be the case for such a significant piece of software. Please help
straighten me out.

Re: The most newbie question ever
Posted by Keith Thomas <ke...@gmail.com>.
OK. I have kept battling through, guessing at the gaps in the getting
started page but the final command to run the hadoop-examples.jar has
blocked me. As far as I can tell there is no hadoop-examples.jar file in
the distribution.
At a higher level I must be doing something wrong. The path I've
*followed*makes it seem as if there are effectively zero getting
started docs. This
cannot be the case for such a significant piece of software. Please help
straighten me out.

Cool. Thanks this should be more straightforward.
The first config file mentioned here,
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
is mapred-site.xml. The instructions say to add some config info to this
file. Navigating to the recommended directory I don't see this file:

Cool. Thanks this should be more straightforward.
The first config file mentioned here,
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
is mapred-site.xml. The instructions say to add some config info to this
file. Navigating to the recommended directory I don't see this file:

Re: The most newbie question ever

Cool. Thanks this should be more straightforward.
The first config file mentioned here,
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
is mapred-site.xml. The instructions say to add some config info to this
file. Navigating to the recommended directory I don't see this file:

Re: The most newbie question ever
Posted by Harsh J <ha...@cloudera.com>.
You've downloaded a binary inclusive release and can just start using
it after configuring it. Mark the extracted path as HADOOP_PREFIX, and
look at $HADOOP_PREFIX/etc/hadoop/ for the config files. Run HDFS and
YARN via the $HADOOP_PREFIX/sbin/start-{dfs,yarn}.sh scripts, and of
course place $HADOOP_PREFIX/bin/ on your PATH.
If you instead prefer installing 2.x RPMs or DEBs, head over to the
Apache Bigtop project at http://bigtop.apache.org to find the rpm/deb
scripts and perhaps also packages from other builders.
Out of the box, for 2.0.3, you may also have to configure the
CapacityScheduler (since its the default now) to be able to run the
YARN services.

You've downloaded a binary inclusive release and can just start using
it after configuring it. Mark the extracted path as HADOOP_PREFIX, and
look at $HADOOP_PREFIX/etc/hadoop/ for the config files. Run HDFS and
YARN via the $HADOOP_PREFIX/sbin/start-{dfs,yarn}.sh scripts, and of
course place $HADOOP_PREFIX/bin/ on your PATH.
If you instead prefer installing 2.x RPMs or DEBs, head over to the
Apache Bigtop project at http://bigtop.apache.org to find the rpm/deb
scripts and perhaps also packages from other builders.
Out of the box, for 2.0.3, you may also have to configure the
CapacityScheduler (since its the default now) to be able to run the
YARN services.

Re: The most newbie question ever
Posted by Harsh J <ha...@cloudera.com>.
You've downloaded a binary inclusive release and can just start using
it after configuring it. Mark the extracted path as HADOOP_PREFIX, and
look at $HADOOP_PREFIX/etc/hadoop/ for the config files. Run HDFS and
YARN via the $HADOOP_PREFIX/sbin/start-{dfs,yarn}.sh scripts, and of
course place $HADOOP_PREFIX/bin/ on your PATH.
If you instead prefer installing 2.x RPMs or DEBs, head over to the
Apache Bigtop project at http://bigtop.apache.org to find the rpm/deb
scripts and perhaps also packages from other builders.
Out of the box, for 2.0.3, you may also have to configure the
CapacityScheduler (since its the default now) to be able to run the
YARN services.

Thank you for your help Mayank. I managed to google for BUILDING.TXT and
discovered I need maven3. I installed maven3.
When I enter the command on the getting started link you sent me this
happens,

Re: The most newbie question ever

Thanks for the great link but sorry it looks like this is going to be a
long process.
Step 1 is: mvn clean install -DskipTests
First of all my OS tells me I need maven but it gives me two choices, maven
and maven 2.
Is there any pre-req info for Hadoop? I've previously guessed I should
installed open jdk 6. This time I guess maven 2. The result of the 'clean
install' is an error,
[ERROR] BUILD ERROR
[INFO]
------------------------------------------------------------------------
[INFO] Cannot execute mojo: clean. It requires a project with an existing
pom.xml, but the build is not using one.
:(
Looking ahead the next instruction is to CD into a folder that does not
exist on my machine,
cd hadoop-mapreduce-project
A little after that the instructions note I must have installed
version 2.4.1 or greater. 2.4.1 of what?
I feel I am missing the point somewhere :(
