First install CentOS 7 (minimal) (CentOS-7.0-1406-x86_64-DVD.iso)

I have download the CentOS 7 ISO here

### Vagrant Box

You can use my vagrant box voor a default CentOS 7, if you are using virtual box

### Be aware that you add the hostname “centos7” in the /etc/hosts

127.0.0.1 centos7 localhost localhost.localdomain localhost4 localhost4.localdomain4

### Add port forwarding to the Vagrantfile located on the host machine. for example:

config.vm.network “forwarded_port”, guest: 50070, host: 50070

### If not root, start with root

### Install wget, we use this later to obtain the Hadoop tarball

### Disable the firewall (not needed if you use the vagrant box)

We install Hadoop in 5 simple steps:
1) Install Java
2) Install Hadoop
3) Configurate Hadoop
4) Start Hadoop
5) Test Hadoop

1) Install Java

### install OpenJDK Runtime Environment (Java SE 7)

2) Install Hadoop

### create hadoop user Torrent mixmeister studio 7 crack.

### login to hadoop

### generating SSH Key

### authorize the key

### set chmod

### verify key works / check no password is needed

### download and install hadoop tarball from apache in the hadoop $HOME directory

3) Configurate Hadoop

### Setup Environment Variables. Add the following lines to the .bashrc

export JAVA_HOME=/usr/lib/jvm/jre
export HADOOP_HOME=/home/hadoop/hadoop-2.5.0
export HADOOP_INSTALL=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export HADOOP_YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
export JAVA_LIBRARY_PATH=$HADOOP_HOME/lib/native:$JAVA_LIBRARY_PATH

### initiate variables

### Put the property info below between the “configuration” tags for each file tags for each file

### Edit $HADOOP_HOME/etc/hadoop/core-site.xml

### Edit $HADOOP_HOME/etc/hadoop/hdfs-site.xml

### copy template

### Edit $HADOOP_HOME/etc/hadoop/mapred-site.xml

### Edit $HADOOP_HOME/etc/hadoop/yarn-site.xml

### set JAVA_HOME
### Edit $HADOOP_HOME/etc/hadoop/hadoop-env.sh and add the following line

export JAVA_HOME=/usr/lib/jvm/jre

4) Start Hadoop

# format namenode to keep the metadata related to datanodes

# run start-dfs.sh script

# check that HDFS is running
# check there are 3 java processes:
# namenode
# secondarynamenode
# datanode

# check there are 2 more java processes:
# resourcemananger
# nodemanager

5) Test Hadoop

### access hadoop via the browser on port 50070

### put a file

### check in your browser if the file is available
