Chapter 6 of Hadoop Learning: Hbase configuration and installation

1. Install Hbase

1) download, pay attention to be compatible with the hadoop version, and choose the stable version is better.

Wget http://mirrors.hust.edu.cn/apache/hbase/hbase-0.98.5/hbase-0.98.5-hadoop2-bin.tar.gz

2) decompression

Tar-zxvf hbase-0.98.5-hadoop2-bin.tar.gz

3) modify conf/hbase-site.xml file

Hbase.rootdir hdfs://MasterServer:9000/hbase hbase.cluster.distributed true hbase.master hdfs://MasterServer:60000 hbase.zookeeper.quorum hadoop1,hadoop2,hadoop3

4) modify conf/regionservers file

MasterServer

SlaveServer

Note: if you do not want to use MasterServer as a HRegionServer, remove MasterServer

5) modify conf/hbase-env.sh file

Export JAVA_HOME=/usr/lib/jvm/jdk1.6/jdk1.6.0_27

Export HBASE_MANAGES_ZK=false # starts the specified ZooKeeper instead of the native ZooKeeper.

Export HBASE_HOME=/home/hadooper/hadoop/hbase-0.98.5

Export HADOOP_HOME=/home/hadooper/hadoop/hadoop-2.5.1

4. Copy the configured hbase to another node

Scp-r hbase-0.98.5 hadooper@SlaveServer:~/hadoop/

5. Enter hbase shell

Bin/hbase shell

HBase Shell; enter 'help' for list of supported commands.

Type "exit" to leave the HBase Shell
