Hi Bejoy,
Thanks for your response. I first started to install on Ubuntu Linux
and ran into a bunch of problems. So, I wanted to back off a bit and
try something simple first. Hence, my attempt to install on my Windows
7 Laptop.
Well, if you tell to us the problems that you have in Ubuntu, we can
give you a hand.
Michael Noll have great tutorials for this:
Running Hadoop on Ubuntu Linux (Single node cluster)
http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
Running Hadoop on Ubuntu Linux (Multi node cluster)
http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-multi-node-cluster/
I am doing the "standalone" mode - as per the documentation (link in
my original email), I don't need ssh unless I am doing the distributed
mode. Is that not correct?
Yes, but I give you the same recommendation that Bejoy said to you: Use
a Unix-based platform for Hadoop, it's more tested and have better
performance than Windows.
Best wishes
Thanks again for responding
Udayini

Hi Udayani
By default hadoop works well for linux and linux based OS. Since
you are on Windows you need to install and configure ssh using
cygwin before you start hadoop daemons.

Hi,
Following is a description of what I am trying to do and the
steps I followed.
GOAL:
a). Install Hadoop 1.0.3
b). Hadoop in a standalone (or local) mode
c). OS: Windows 7
STEPS FOLLOWED:
1. 1. I followed instructions from:
http://www.oreillynet.com/pub/a/other-programming/excerpts/hadoop-tdg/installing-apache-hadoop.html.
Listing the steps I did -
a.I went to: http://hadoop.apache.org/core/releases.html.
b.I installed hadoop-1.0.3 by downloading
“hadoop-1.0.3.tar.gz” and unzipping/untarring the file.
c.I installed JDK 1.6 and set up JAVA_HOME to point to it.
d.I set up HADOOP_INSTALL to point to my Hadoop install
location. I updated my PATH variable to have $HADOOP_INSTALL/bin
e.After the above steps, I ran the command: “hadoop version”
and got the following information:
$ hadoop version
Hadoop 1.0.3
Subversion
https://svn.apache.org/repos/asf/hadoop/common/branches/branch-1.0
-r 1335192
Compiled by hortonfo on Tue May 8 20:31:25 UTC 2012
From source with checksum e6b0c1e23dcf76907c5fecb4b832f3be
2. 2. The standalone was very easy to install as
described above. Then, I tried to run a sample command as
given in:
http://hadoop.apache.org/common/docs/r0.17.2/quickstart.html#Local
Specifically, the steps followed were:
a.cd $HADOOP_INSTALL
b.mkdir input
c.cp conf/*.xml input
d.bin/hadoop jar hadoop-examples-1.0.3.jar grep input output
‘dfs[a-z.]+’
and got the following error:
$ bin/hadoop jar hadoop-examples-1.0.3.jar grep input output
'dfs[a-z.]+'

3. 3. I googled the problem and found the following links
but none of these suggestions helped.Most people seem to be
getting a resolution when they change the version of Hadoop.
a.http://mail-archives.apache.org/mod_mbox/hadoop-common-user/201105.mbox/%3cbanlktin-8+z8uybtdmaa4cvxz4jzm14...@mail.gmail.com%3E
b.http://comments.gmane.org/gmane.comp.jakarta.lucene.hadoop.user/25837
Is this a problem in the version of Hadoop I selected OR am I
doing something wrong? I would appreciate any help with this.
Thanks
Udayini
