HAdoop 2.0.* Single node setup

[nagarjuna kanamarlapudi <na...@gmail.com>]

Hi,

It is a bit fuzzy from the documentation of single node cluster setup of
hadoop 2.0.*

Can some one help me out in doing the same.

I downlaoded hadoop-2.0.3-alpha.tar.gz
Extracted them into folder hadoop-2.0.3-alpha
I find the follwoing folders
1)bin
2)etc
3)include
4)lib
5)libexec
6)sbin
7)share



As far as what is mentioned in
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html#Hadoop_MapReduce_Next_Generation_-_Setting_up_a_Single_Node_Cluster


Assuming you have installed hadoop-common/hadoop-hdfs and exported *
$HADOOP_COMMON_HOME*/*$HADOOP_HDFS_HOME*, untar hadoop mapreduce tarball
and set environment variable *$HADOOP_MAPRED_HOME* to the untarred
directory. Set *$HADOOP_YARN_HOME* the same as *$HADOOP_MAPRED_HOME*.


what is this
1)HADOOP_COMMON_HOME
2)*HADOOP_HDFS_HOME*
*3)**HADOOP_MAPRED_HOME*
*4)**HADOOP_YARN_HOME*
