Build a Hadoop 2.7.3 cluster in CentOS 6.7
Hadoop clusters have three operating modes: Standalone mode, pseudo distribution mode, and full distribution mode. Here we set up the third full distribution mode, that is, using a distributed system to run on multiple nodes.1. Configure DNS in Environment 1.1
Go to the configuration file and add the ip ing between the
Install and configure the hadoop plug-in myeclipse and eclipse in windows/Linux, and myeclipsehadoop
I recently want to write a test program MaxMapperTemper on windows, and there is no server around, so I want to configure it on windows 7.
Succeeded. I want to take notes here to help you.
The installation and configuration steps are as follows:

Hadoop
Virtual machine to build Hadoop's full distributed cluster-in detail (1), set up three virtual machine master, Slave1 and Slave2 hostname and IP address, so that the host can ping each other. This blog will continue to prepare virtual machines for a fully distributed Hadoop cluster, with the goal of enabling Master, Slave1, and Slave2 to log on to each other via

4. sudo tar-zxf jdk-7u45-linux-x64.tar.gz (Note: extract)
5. sudo gedit ~ /. Bashrc (Note: Modify the bashrc file in the root directory to set java environment variables)
Append the following content to bashrc:Export JAVA_HOME =/usr/java/jdk1.7.0 _ 45
Export CLASSPATH =.: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar
Export PATH = $ PATH: $ JAVA_HOME/bin6. Close the current terminal window and open another terminal window

In the terminal input command: Apt-cache search openjdk Find the JDK version we need to install from the list of searches to execute the install command: sudo apt-get install OPENJDK-7-JDK Note OPENJDK-7-
First we need to prepare the following environment and software:1.7. 9-1jdk-6u25-windows-x64.ziphadoop-0.20. 2. tar.gz1. Install the JDK properly on the Win7 system, while keeping in mind that the variables for the Java environment are set up:The main variables include: Java_home,path,classpath(Please bring your own ladder if not set)2. Next is the installation of Hadoop, I am currently installing version 0
Percona XtraDB Cluster how to install two Cluster nodes on one server
I think it makes no sense to run two or more Percona XtraDB Cluster (PXC) nodes on a single physical server, except for educational and testing purposes, however, this method is still useful in this case. The most popular implementation method seems
When a problem occurs in a single node of a Hadoop cluster, it is generally not necessary to restart the entire system, just restart the node and it will automatically connect to the entire cluster.Enter the following command on the necrotic node:hadoop-daemon.sh Start Datanodehadoop-daemon.sh Start SecondarynamenodeThe cases are as follows:Hadoop node crashes, can ping Pass, SSH Connection not onCase:Time:
Install SSH
Hadoop uses SSH for communication. In this case, we need to set the password to null, that is, no password is required to log on. This eliminates the need to enter a secret during each communication. The installation is as follows:
Enter "Y" for installation and wait for the automatic installation to complete.
Start the service after installing SSH
Run the following command to verify that t
mytable from Database mydb to the E:\MySQL\mytable.sql file.
c:\> mysqldump-h localhost-u root-p mydb mytable>e:\mysql\mytable.sql
Example 3: Export the structure of the database mydb to a e:\MySQL\mydb_stru.sql file.
c:\> mysqldump-h localhost-u root-p mydb--add-drop-table >e:\mysql\mydb_stru.sql
Note :-h localhost can be omitted, it is generally used on the virtual host.3) Export data structure onlyformat : mysqldump-u [Database user name]-p-t [the name of the data
localhost-u root-p mydb >e:\mysql\mydb.sql
Then enter the password, wait for an export to succeed, you can check the target file for success. Example 2: Export mytable from Database mydb to the E:\MySQL\mytable.sql file.
c:\> mysqldump-h localhost-u root-p mydb mytable>e:\mysql\mytable.sql
Example 3: Export the structure of the database mydb to a e:\MySQL\mydb_stru.sql file.
c:\> mysqldump-h localhost-u root-p mydb--add-drop-table >e:\mysql\mydb_stru.sql
