Current version of admin_Hadoop.md contains an 
obsolete set of instructions.Changes are purely 
textual; no code changes.Linking to a community 
site extends the viability of the doc and allows 
instructions to keep pace with future versions.
Instructions have been validated.

-##Preparing to Install Hadoop Compatible Storage
-
-This section provides information on pre-requisites and list of
-dependencies that will be installed during installation of Hadoop
-compatible storage.
-
 ###Pre-requisites
 
 The following are the pre-requisites to install Hadoop Compatible
 Storage :
 
--   Hadoop 0.20.2 is installed, configured, and is running on all the
-    machines in the cluster.
 -   Java Runtime Environment
--   Maven (mandatory only if you are building the plugin from the
-    source)
--   JDK (mandatory only if you are building the plugin from the source)
 -   getfattr - command line utility
 
 ##Installing, and Configuring Hadoop Compatible Storage
 
-This section describes how to install and configure Hadoop Compatible
-Storage in your storage environment and verify that it is functioning
-correctly.
-
-1.  Download `glusterfs-hadoop-0.20.2-0.1.x86_64.rpm` file to each
-    server on your cluster. You can download the file from [][].
-
-2.  To install Hadoop Compatible Storage on all servers in your cluster,
-    run the following command:
-
-    `# rpm –ivh --nodeps glusterfs-hadoop-0.20.2-0.1.x86_64.rpm`
-
-    The following files will be extracted:
-
-        - /usr/local/lib/glusterfs-Hadoop-version-gluster\_plugin\_version.jar
-        - /usr/local/lib/conf/core-site.xml
-
-3.  (Optional) To install Hadoop Compatible Storage in a different
-    location, run the following command:
-
-    `# rpm –ivh --nodeps –prefix /usr/local/glusterfs/hadoop glusterfs-hadoop- 0.20.2-0.1.x86_64.rpm`
-
-4.  Edit the `conf/core-site.xml` file. The following is the sample
-    `conf/core-site.xml` file:
-
-        <configuration>
-          <property>
-            <name>fs.glusterfs.impl</name>
-            <value>org.apache.hadoop.fs.glusterfs.Gluster FileSystem</value>
-        </property>
-
-        <property>
-           <name>fs.default.name</name>
-           <value>glusterfs://fedora1:9000</value>
-        </property>
-
-        <property>
-           <name>fs.glusterfs.volname</name>
-           <value>hadoopvol</value>
-        </property>  
-         
-        <property>
-           <name>fs.glusterfs.mount</name>
-           <value>/mnt/glusterfs</value>
-        </property>
-
-        <property>
-           <name>fs.glusterfs.server</name>
-           <value>fedora2</value>
-        </property>
-
-        <property>
-           <name>quick.slave.io</name>
-           <value>Off</value>
-        </property>
-        </configuration>
-
-    The following are the configurable fields:
-
-	Property Name | Default Value | Description
-	--- | --- | ---	
-	fs.default.name | glusterfs://fedora1:9000 | Any hostname in the cluster as the server and any port number.
-	fs.glusterfs.volname | hadoopvol | GlusterFS volume to mount.
-	fs.glusterfs.mount | /mnt/glusterfs | The directory used to fuse mount the volume.
-	fs.glusterfs.server | fedora2 | Any hostname or IP address on the cluster except the client/master.
-	quick.slave.io | Off | Performance tunable option. If this option is set to On, the plugin will try to perform I/O directly from the disk file system (like ext3 or ext4) the file resides on. Hence read performance will improve and job would run faster. **Note*: This option is not tested widely
-
-5.  Create a soft link in Hadoop’s library and configuration directory
-    for the downloaded files (in Step 3) using the following commands:
-
-    `# ln -s >`
-
-    For example,
-
-    `# ln –s /usr/local/lib/glusterfs-0.20.2-0.1.jar /lib/glusterfs-0.20.2-0.1.jar`
-    `# ln –s /usr/local/lib/conf/core-site.xml /conf/core-site.xml `
-
-6.  (Optional) You can run the following command on Hadoop master to
-    build the plugin and deploy it along with core-site.xml file,
-    instead of repeating the above steps:
-
-    `# build-deploy-jar.py -d  -c `
-
-##Starting and Stopping the Hadoop MapReduce Daemon
-
-To start and stop MapReduce daemon
-
--   To start MapReduce daemon manually, enter the following command:
-
-    `# /bin/start-mapred.sh`
-
--   To stop MapReduce daemon manually, enter the following command:
-
-    `# /bin/stop-mapred.sh `
-
-> **Note**
-> You must start Hadoop MapReduce daemon on all servers.
