HBase伪分布式安装与JAVA基本操作

2019年6月9日 145次阅读来源: 像鸣人

CentOS单机安装

参照：https://www.yiibai.com/hadoop/

配置ssh

参照：https://blog.csdn.net/liaoguolingxian/article/details/70233910

下载 & 安装 hadoop

下载：http://www-eu.apache.org/dist/hadoop/common/hadoop-2.8.4/hadoop-2.8.4.tar.gz

安装：tar -xzvf hadoop-2.8.4.tar.gz -C /usr/local/hadoop

配置环境变量：

export HADOOP_HOME=/usr/local/hadoop
export PATH=$HADOOP_HOME/bin:$PATH

hadoop配置文件

目录 hadoop/etc

core-site.xml

<property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:9000</value> 
</property>

hdfs-site.xml

<property>
  <name>dfs.replication</name>
  <value>1</value>
</property>
<property>
  <name>dfs.name.dir</name>
  <value>file:///home/docker/hadoop/hdfs/namenode</value>
</property>
<property>
  <name>dfs.data.dir</name> 
  <value>file:///home/docker/hadoop/hdfs/datanode</value> 
</property>

yarn-site.xml

<property>
  <name>yarn.nodemanager.aux-services</name>
  <value>mapreduce_shuffle</value> 
</property>

mapred-site.xml

<property> 
  <name>mapreduce.framework.name</name>
  <value>yarn</value>
</property>

启动hadoop

修改 home/docker/hadoop/hdfs 权限
chmod 777 -R home/docker/hadoop/hdfs
格式化hadoop
hdfs namenode -format
启动
hadoop/sbin/start-all.sh

一些命令

查看文件列表
hadoop fs -ls /

创建目录
hadoop fs -mkdir -p /user/input

上传文件
hadoop fs -put file.txt /user/input

查看文件内容
hadoop fs -cat /user/input/file.txt

下载文件
hadoop fs -get /user/input/ tmp

打开/关闭 hadoop 调试日志

export HADOOP_ROOT_LOGGER=DEBUG,console
export HADOOP_ROOT_LOGGER=INFO,console

安装 HBase

下载：http://archive.apache.org/dist/hbase/2.0.0/hbase-2.0.0-bin.tar.gz
解压：tar -xzvf hbase-2.0.0-bin.tar.gz
移动：mv hbase-2.0.0 /usr/local/hbase
配置映射：参照：https://blog.csdn.net/qq_31570685/article/details/51757604

/etc/hosts中添加映射

192.168.1.199   zk_master

192.168.1.199 为本机IP，zk_master 为映射名，可随意指定

经测试，此步（5）可以不执行

修改静态IP

使用 ifconfig 查看本机使用 IP 配置
cd /etc/sysconfig/network-scripts，ls 找到IP配置
修改 DEVICE=zk_master 保存，退出

添加环境变量：

export HBASE_HOME=/usr/local/hbase

修改HBase配置

hbase-env.sh

export JAVA_HOME=/usr/java/jdk1.8.0_171-amd64
export HBASE_MANAGES_ZK=true

hbase-site.xml

<property>
    <name>hbase.rootdir</name>
    <value>hdfs://192.168.1.199:9000/hbase</value>
</property>
<property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
</property>
<property>
    <name>hbase.zookeeper.quorum</name>
    <value>zk_master</value>
</property>
<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/docker/hadoop/hbase/zk/data</value>
</property>
<property>  
    <name>hbase.tmp.dir</name>  
    <value>/home/docker/hadoop/hbase/tmp</value>  
</property>

启动之
/usr/local/hbase/start-hbase.sh
关闭之

/usr/local/hbase/start-hbase.sh

此命令偶尔会出现长时间阻塞无法关闭的现象，则可使用下面命令关闭

使用 ls -1 /tmp |grep hbase-查看/tmp下所有hbase相关的文件，找出*.pid后缀的文件执行下面指令：

cat /tmp/hbase-user-zookeeper.pid |xargs kill -9
cat /tmp/hbase-user-master.pid |xargs kill -9
cat /tmp/hbase-user-1-regionserver.pid |xargs kill -9

4、5这2步一直是看到上文的文章（4中的参照）才解决的，4、5不配置，本机命令行操作不存在问题，但远程是无法成功连接的，这个地方卡了3天才解决，汗！！！

JAVA操作

基本java api实现；commons-pool2连接池；类结构如下：

本来计划是用spring-boot/spring-data-hadoop实现的，由于种种原因还是先选择了使用基本java api先实现，上面很多jar用不上，可以尝试删除，也可以直接无视，不影响正常运行！

添加配置文件：hbase-site.xml
