Install Hadoop with HDP 2.2 on CentOS 6.5
Hadoop HortonworksMasters-- HDFS NameNode, YARN ResourceManager (ApplicationsManager + Scheduler), and HBase Master
Slaves-- HDFS DataNodes, YARN NodeManagers, and HBase RegionServers (Worker Nodes co-deployed)
ZooKeeper -- to manage HBase cluster
HA -- NameNode + Secondary NameNode 或者NameNode HA (Active + Standby)，推荐后者
分区考虑，不要使用LVM
root -- > 100G
/tmp -- >100G (run job失败的话请查看此目录空间)
swap -- 2倍系统内存
Master node:
RAID 10, dual Ethernet cards, dual power supplies, etc.
Slave node:
1. RAID is not necessary
2. HDFS分区, not using LVM
/etc/fstab -- ext3/ext4 defaults,noatime
挂载到/grid/ (one partition per disk)

For ambari/hive/oozie database:
yum -y install ambari-server
mysql -uroot -p
create database ambari;
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost'>
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%'> flush privileges;
use ambari;

Install mysql jdbc connector:
tar zxf mysql-connector-java-5.1.33.tar.gz
mkdir /usr/share/java
cp mysql-connector-java-5.1.33/mysql-connector-java-5.1.33-bin.jar /usr/share/java/mysql-connector-java.jar
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
ambari-server setup -j /usr/java/default
Enter advanced database configuration (n)? y
choose to use mysql, enter 3
ambari-server start
http://{your.ambari.server}:8080
default user name/password: admin/admin
使用Pi Estimator验证测试：
sudo -u hdfs hadoop jar /usr/hdp/version-number/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 10 1000
关机的正确步骤：
1. stop all service in Ambari Web UI (if there is no response for stopping, service ambari-server restart, then try again)
2. poweroff hosts
Enable HA for NameNode and ResourceManager
HUE installation:
we will install HUE on client node:
The Hive client configuration (hive-site.xml file) needs to be populated on the host to run Hue. In the beeswax section of hue.ini configure:
hive_conf_dir=/etc/hive/conf
Configure HDP
1. Modify the core-site.xml
2. Modify the webhcat-site.xml file
3. Modify the oozie-site.xml file
yum -y install hue
vi /etc/hue/conf/hue.ini
