hbase 安装笔记
1、安装
在官方镜像站点下载hbase2.0，地址：https://www.apache.org/dyn/closer.lua/hbase/
解压
tar xzvf hbase-2.0.4-bin.tar.gz
设置好JAVA_HOME环境变量，或者直接在hbase的配置文件(conf/hbase-env.sh)里设置JAVA_HOME
设置HBASE_HOME，这个不是必须。
本例是在/etc/profile文件里追加java环境变量，设置后需要source /etc/profile使设置生效，或者重新登录
#set java environment JAVA_HOME=/home/java/jdk1.8.0_172 JRE_HOME=/home/java/jdk1.8.0_172/jre CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin export JAVA_HOME JRE_HOME CLASS_PATH PATH #set hbase environment export HBASE_HOME=/opt/hbase-2.0.4 export PATH=$PATH:$HBASE_HOME/bin
2、配置hbase-site.xml
vi $HBASE_HOME/conf/hbase-site.xml <configuration> <property>
#hbase的数据目录 <name>hbase.rootdir</name> <value>file:///opt/hbase_data</value> #本例使用本地文件系统，如果是需要把数据存在hdfs上，需配置相应的hdfs目录，例如：hdfs://namenode.example.org:9000/hbase </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/opt/hbase_data/zookeeper</value> </property> <property> <name>hbase.unsafe.stream.capability.enforce</name> <value>false</value> </property> </configuration>
3、启动hbase，在standalone模式下hbase所有守护进程都运行在一个JVM里，例如：HMaster、HRegionServer、ZooKeeper daemon等。
执行在hbase的bin目录下的脚本 bin/start-hbase.sh
启动后通过jps可以看到hMaster的进程 [root@bigdata-senior01 ~]# jps 2082 Jps 1523 HMaster
4、进入shell，通过hbase的bin目录下的bin/hbase shell启动
[hadoop@bigdata-senior01 conf]$ hbase shell SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/opt/hbase-2.0.4/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/opt/hadoop/hadoop-3.2.0/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory] HBase Shell Use "help" to get list of supported commands. Use "exit" to quit this interactive shell. For Reference, please visit: http://hbase.apache.org/2.0/book.html#shell Version 2.0.4, r205e39c5704bf38568b34926dde9f1ee76e6b5d0, Fri Dec 28 22:13:42 PST 2018 Took 0.0220 seconds
5、检查hbase是否正常
hbase(main):004:0> status 1 active master, 0 backup masters, 1 servers, 0 dead, 2.0000 average load Took 0.0159 seconds
5.1、hbase的WEB UI
http://主机:16010
6、基本的表操作
6.1、建表
hbase(main):005:0> create 'test','c01f01' Created table test Took 0.8601 seconds => Hbase::Table - test hbase(main):007:0> list 'test' TABLE test 1 row(s) Took 0.0213 seconds => ["test"]
hbase(main):004:0> desc 'test'
Table test is ENABLED
test
