+
+* Mapreduce Tarball
+
+  You should be able to obtain the MapReduce tarball from the release.
+  If not, you should be able to create a tarball from the source.
+
++---+
+$ mvn clean install -DskipTests
+$ cd hadoop-mapreduce-project
+$ mvn clean install assembly:assembly 
++---+
+  <<NOTE:>> You will need protoc installed of version 2.4.1 or greater.
+
+  To ignore the native builds in mapreduce you can use <<<-P-cbuild>>>
argument
+  for maven. The tarball should be available in <<<target/>>> directory.

+
+  
+* Setting up the environment.
+
+  Assuming you have installed hadoop-common/hadoop-hdfs and exported
+  <<$HADOOP_COMMON_HOME>>/<<$HADOOP_COMMON_HOME>>, untar hadoop mapreduce

+  tarball and set environment variable <<$HADOOP_MAPRED_HOME>> to the 
+  untarred directory. Set <<$YARN_HOME>> the same as <<$HADOOP_MAPRED_HOME>>.

+ 
+  <<NOTE:>> The following instructions assume you have hdfs running.
+
+* Setting up Configuration.
+
+  To start the ResourceManager and NodeManager, you will have to update the configs.
+  Assuming your $HADOOP_CONF_DIR is the configuration directory and has the installed
+  configs for HDFS and <<<core-site.xml>>>. There are 2 config files you
will have to setup
+  <<<mapred-site.xml>>> and <<<yarn-site.xml>>>.
+
+** Setting up <<<mapred-site.xml>>>
+
+  Add the following configs to your <<<mapred-site.xml>>>.
+
++---+
+  <property>
+    <name>mapreduce.cluster.temp.dir</name>
+    <value></value>
+    <description>No description</description>
+    <final>true</final>

+    <description>No description</description>
+    <final>true</final>
+  </property>
++---+
+
+** Setting up <<<yarn-site.xml>>>
+
+Add the following configs to your <<<yarn-site.xml>>>
+
++---+
+ <property>
+    <name>yarn.resourcemanager.resource-tracker.address</name>
+    <value>host:port</value>
+    <description>host is the hostname of the resource manager and

+ </property>
+
+ <property>
+    <name>yarn.resourcemanager.scheduler.address</name>
+    <value>host:port</value>
+    <description>host is the hostname of the resourcemanager and port is the port
+    on which the Applications in the cluster talk to the Resource Manager.
+    </description>
+  </property>
+
+  <property>
+    <name>yarn.resourcemanager.scheduler.class</name>
+    <value>org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler</value>

+  </property>
+
+  <property>
+    <name>yarn.resourcemanager.address</name>
+    <value>host:port</value>
+    <description>the host is the hostname of the ResourceManager and the port is the
port on
+    which the clients can talk to the Resource Manager. </description>
+  </property>
+

+    <value>mapreduce.shuffle</value>
+    <description>shuffle service that needs to be set for Map Reduce to run </description>
+  </property>
++---+
+
+* Create Symlinks.
+
+  You will have to create the following symlinks:
+
++---+
+$ cd $HADOOP_COMMON_HOME/share/hadoop/common/lib/
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-mapreduce-client-app-*-SNAPSHOT.jar .
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-mapreduce-client-jobclient-*-SNAPSHOT.jar .
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-mapreduce-client-common-*-SNAPSHOT.jar .
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-mapreduce-client-shuffle-*-SNAPSHOT.jar .
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-mapreduce-client-core-*-SNAPSHOT.jar .
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-yarn-common-*-SNAPSHOT.jar .
+$ ln -s $HADOOP_MAPRED_HOME/modules/hadoop-yarn-api-*-SNAPSHOT.jar .
++---+
+* Running daemons.
+
+  Assuming that the environment variables <<$HADOOP_COMMON_HOME>>, <<$HADOOP_HDFS_HOME>>,
<<$HADOO_MAPRED_HOME>>,
+  <<$YARN_HOME>>, <<$JAVA_HOME>> and <<$HADOOP_CONF_DIR>>
have been set appropriately.
+  Set $<<$YARN_CONF_DIR>> the same as $<<HADOOP_CONF_DIR>>
+ 
+  Run ResourceManager and NodeManager as:
+  
++---+
+$ cd $HADOOP_MAPRED_HOME
+$ bin/yarn-daemon.sh start resourcemanager
+$ bin/yarn-daemon.sh start nodemanager
++---+
+
+  You should be up and running. You can run randomwriter as:
+
++---+
+$ $HADOOP_COMMON_HOME/bin/hadoop jar hadoop-examples.jar randomwriter out
++---+
+
+Good luck.

+
+Hadoop MapReduce Next Generation
+
+* Architecture
+
+  The new architecture introduced in 0.23, divides the two major functions 
+  of the JobTracker, resource management and job scheduling/monitoring, into separate 
+  components. 
+  The new ResourceManager manages the global assignment of compute resources to applications

+  and the per-application ApplicationMaster manages the application’s scheduling and
coordination.
+  An application is either a single job in the classic MapReduce jobs or a DAG of such jobs.

+  The ResourceManager and per-machine NodeManager server, which manages the user processes
on that 
+  machine, form the computation fabric. The per-application ApplicationMaster is, in effect,
a 
+  framework specific library and is tasked with negotiating resources from the ResourceManager

+  and working with the NodeManager(s) to execute and monitor the tasks.
