I'm attempting to setup the pseudo-distributed config on a mac 10.6.8.
I followed the steps from the QuickStart
(http://wiki.apache.org./hadoop/QuickStart) and succeeded with Stage
1: Standalone Operation.
I followed the steps for Stage 2: Pseudo-distributed Configuration.
I set the JAVA_HOME variable in conf/hadoop-env.sh and I changed
tools.jar to the location of classes.jar (a mac version of tools.jar)
I've modified the three .xml files as described in the QuickStart.
ssh'ing to localhost has been configured and works with passwordless
authentication.
I formatted the namenode with "bin/hadoop namenode -format" as the
instructions say
This is what I see when I run bin/start-all.sh
root# bin/start-all.sh

There are 4 processes running:
ps -fax | grep hadoop | grep -v grep | wc -l
4
They are:
SecondaryNameNode
TaskTracker
NameNode
JobTracker
I've searched to see if anyone else has encountered this and not found
anything
