A record--Offline deployment of Big Data Platform CDH Cluster

Tags： Cloudera-Manager CDH Hadoop Deploy Cluster

Abstract: Deployment and Management of Hadoop clusters need tools, such as Cloudera Manager. In this article, I compare the tools briefly, and then record the step of deploying CDH cluster offline in detail. Finally, I expound the theory of 'handle delicately'.

A record--Offline deployment of Big Data Platform CDH Cluster

Preface

The emergence of Big Data technology led by Apache Hadoop, makes small and medium-sized enterprises also have the ability to handle the storage and processing of big data. At present, there'r lots of Hadoop distributions, such as HUAWEI Distribution, Intel Distribution, Cloudera’s Distribution Including Apache Hadoop (CDH free), and Hortonworks Data Platform (HDP free), etc. All of these are based on the Hadoop Apache Community Edition.

The deployment and management of a Hadoop cluster which has tens or more nodes needs advanced tools. Apache Ambari from Hortonworks is this kind of tools, it provided an easy-to-use RESTfull web site to manage Hadoop. Cloudera also provided a similar tool, Cloudera Manager(CM) to configure, monitor and manage CDH clusters.

The main content of this paper is a record of building a CDH cluster. Special attention is required to choose Cloudera Manager version, which depends on Operating system, el7 isn't supported by Cloudera Manager at this moment. You should follow [the official document][1], otherwise the installation will run into a stone wall.

This paper is based on CentOS 6.5, 64-bit；Cloudera Manager 5.3.6；JDK 1.7.

Deploy CDH

Configure network (All nodes)

[root@cdh-server ~]# vi /etc/sysconfig/network #修改hostname:
NETWORKING=yes
HOSTNAME=cdh-server
[root@cdh-server ~]# vi /etc/hosts #修改ip与主机名的对应关系:
192.168.180.173 cdh-server
192.168.180.175 node175
[root@cdh-server ~]# service network restart #重启网络服务生效

Install JDK (All nodes)

#卸载OpenJDK
[root@cdh-server user1]# rpm -qa | grep java
[root@cdh-server user1]# rpm -e --nodeps java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
[root@cdh-server user1]# rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
[root@cdh-server user1]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64

# Uncomment the following if you are using InnoDB tables
innodb_data_home_dir = /home/user1/mysql-5.6.26/data
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /home/user1/mysql-5.6.26/data
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 5M

The theory of handle delicately

Handle delicately is a kind of feeling, but also a skill. When in seller's market, a company can make a profit while may needn't to handle delicately. However, if it wishes to pursue more, it will handle more delicately, such as pay more attention to detail, User Experience or others. When in buyer's market, the relation between supply and demand makes companies handle delicately to survive.

Handle delicately is not only the driving force pushing social to continually advance, but also the result of this advance. Today, lots of internet firms are in buyer's market, who has more users who will win the fight, delicately handling makes them at the forefront of social evolution and technological innovation.

Handle delicately doesn't only appear in companies, but also individuals, regions and countries, etc. The contry who handles more delicately, who is more developed. The company who pays more attention to details, who is more competitive. But, the one who handles more delicately doesn't mean it will make more profits, for various reasons.
