HBase介绍
HBase – Hadoop Database,是一个高可靠性、高性能、面向列、可伸缩的分布式存储系统,利用HBase技术可在廉价PC Server上搭建起大规模结构化存储集群。
HBase是Google Bigtable的开源实现,类似Google Bigtable利用GFS作为其文件存储系统,HBase利用Hadoop HDFS作为其文件存储系统;Google运行MapReduce来处理Bigtable中的海量数据,HBase同样利用Hadoop MapReduce来处理HBase中的海量数据。
上图描述了Hadoop EcoSystem中的各层系统,其中HBase位于结构化存储层,Hadoop HDFS为HBase提供了高可靠性的底层存储支持,Hadoop MapReduce为HBase提供了高性能的计算能力,Zookeeper为HBase提供了稳定服务和failover机制。
此外,Pig和Hive还为HBase提供了高层语言支持,使得在HBase上进行数据统计处理变的非常简单。 Sqoop则为HBase提供了方便的RDBMS数据导入功能,使得传统数据库数据向HBase中迁移变的非常方便。
把下载好的包 传到/home/hadoop/hbase 解压后:
[hadoop@master hbase]$ ll total 788 drwxr-xr-x. 4 hadoop hadoop 4096 Dec 5 10:53 bin -rw-r--r--. 1 hadoop hadoop 228302 Dec 5 10:58 CHANGES.txt drwxr-xr-x. 2 hadoop hadoop 4096 Dec 5 10:54 conf drwxr-xr-x. 12 hadoop hadoop 4096 Dec 5 11:53 docs drwxr-xr-x. 7 hadoop hadoop 4096 Dec 5 11:43 hbase-webapps -rw-r--r--. 1 hadoop hadoop 261 Dec 5 11:56 LEGAL drwxrwxr-x. 3 hadoop hadoop 4096 Jan 8 11:10 lib -rw-r--r--. 1 hadoop hadoop 143082 Dec 5 11:56 LICENSE.txt -rw-r--r--. 1 hadoop hadoop 404470 Dec 5 11:56 NOTICE.txt -rw-r--r--. 1 hadoop hadoop 1477 Dec 5 10:53 README.txt
设置环境变量
[root@master master]# vi /etc/profile
export HBASE_HOME=/home/hadoop/hbase
export PATH=$PATH:$HBASE_HOME/bin
[root@master master]# source /etc/profile
[hadoop@master ~]$ hbase version
HBase 1.4.9
