Enable EFI Support

    Extensible Firmware Interface (EFI) is replacing BIOS as a technology that newer computers and operating systems use to boot computers. EFI is sometimes referred to as Unified Extensible Firmware Interface (UEFI).
   You can choose to boot a virtual machine by using the EFI firmware option or select BIOS in the New Virtual Machine wizard when you choose use a custom configuration.
   You can specify the EFI firmware option when you create a remote virtual machine in shared virtual machine mode.

Prerequisites

Verify that the following conditions are met:
 
1、The guest operating system to be installed on the virtual machine supports EFI firmware.
 
2、The virtual machine uses hardware version 8 or later.
 
3、The software to boot the system is installed.
 
Procedure

1、In the Workstation interface select VM > Settings. 
 
2、Click the Options tab and click Advanced. 
 
3、Click Boot with EFI instead of BIOS check box.
4、Click OK.

修改后缀名为 vmx 配置文件
添加行：
bios.bootDelay = "10000"      //延迟10秒进入系统
firmware = "efi"                    //支持efi

环境：VMware+Ubuntu16.04+Hadoop2.7.7+jdk1.8.0


1、超稳进入BIOS，开启虚拟技术，Intel VT-x


左下角右键，设置，更新和安全，恢复，立即重新启动。疑难解答，高级选项，UEFI固件设置，重启。即可进入BIOS

选择configuration Intel virtual technology 选择Enable。


2、新建一个用户


sudo useradd –m hadoop –s /bin/bash

sudo passwd hadoop

sudo adduser hadoop sudo

在该用户下进行Hadoop安装


3、新建java环境 


sudo apt-get install openjdk-8-jre openjdk-8-jdk

该种方法安装的java无需添加路径

检测Java是否安装好：java -version

如果要添加 gedit ~/.bashrc

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 export PATH=$JAVA_HOME/bin:$PATH


4、下载Hadoop


下载Hadoop用镜像，wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.7.7/hadoop-2.7.7.tar.gz

sudo tar -zxf ~/下载/hadoop-2.6.0.tar.gz -C /usr/local    #解压到/usr/local中

cd /usr/local/ $sudo mv ./hadoop-2.6.0/ ./hadoop            # 将文件夹名改为hadoop

sudo chown -R hadoop:hadoop ./hadoop       # 修改文件权限

检验是否安装好Hadoop

cd /usr/local/hadoop

./bin/hadoop version


5、配置Hadoop


修改配置文件：core-site.xml，hdfs-site.xml，mapred-site.xml

初始化文件系统hadoop namenode -format

启动所有进程start-all.sh

访问web界面，查看Hadoop信息

运行实例

-----------------------------------------------------

core-site.xml

<configuration>
    <property>
        <name>hadoop.tmp.dir</name>
        <value>file:/usr/local/hadoop/tmp</value>
        <description>Abase for other temporary directories.</description>
    </property>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>


 hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>file:/usr/local/hadoop/tmp/dfs/name</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
       <value>file:/usr/local/hadoop/tmp/dfs/data</value>
    </property>
</configuration>


 mapred-site.xml

<configuration>
    <property>
        <name>mapred.job.tracker</name>
        <value>localhost:9001</value>
    </property>
</configuration>

验证Hadoop是否安装好：hadoop version

初始化HDFS系统：hadoop namenode -format



进入/usr/local/hadoop 

sbin/start-all.sh

输入jps



此时hadoop安装成功

-----------

在浏览器中输入：http://localhost:50070，http://localhost:8088



 

 

    
对于同时支持legacy BIOS和UEFI的机器，如果需要在VMware HCL上声明同时对BIOS和UEFI的支持需要：
1.在BIOS上运行完整的server 认证（也可以是UEFI上），并将结果提交给VMWARE
2.对UEFI模式做重认证（如果上步是UEFI的，这步就是对BIOS做重认证），并且只需要运行：
BIOS or UEFI Update Supported Platform
Note: If you are certified for TXT support and the BIOS
or UEFI platform changes, you must re-run additional
TXT tests. See page 59 for details.
 System Check
 Health State and Hardware Collector
 Multi-GOS-Network-Stress
 Multi-GOS-Storage-Stress
 DPM tests‘
这些测试，然后将结果提交给vmware
3.搞定
获取对DPM的认证：
如果机器支持wol，和/或者IPMI或者ilo/ilo2(HP 管理工具)，那么必须要测试DPM，该测试如果没做，会在vmware compatibility guide（VCG）中增加一个脚注，来说明vcenter不支持该产品的DPM（5.1u1的时候该项也为强制项，但是没说如果不做就会增加不支持的脚注，根据实际情况看，也确实是这样，这个需要注意）
获得：VMDirectPath I/O, SR-IOV, or TXT Certification认证：
在做这些认证前，必须要通过server certification.
