I. Overview

My machine uses the hadoop-2.7.2,hbase-1.1.3 version and the system is ubuntu14.

Hadoop installation: previous article

II. Installation of HBase

Download address: http://mirrors.noc.im/apache/hbase/stable/

1. Modify the hbase-env.sh configuration file to use the zookeeper that comes with hbase

Export JAVA_HOME=/home/ubuntu/jdk1.7.0_10/export HBASE_CLASSPATH=/home/ubuntu/hbase-1.1.3/confexport HBASE_MANAGES_ZK=true

two。 Modify hbase-site.xml configuration file

Hbase.rootdir hdfs://localhost:9000/hbase hbase.zookeeper.property.dataDir / home/hadoop/softwares/hbase-1.1.3/data/zkData hbase.cluster.distributed true

3. Modify the regionservers configuration file to add the machine name

Localhost

4. Start hadoop before starting hbase

Start hbase

Bin/hbase-daemon.sh start zookeeperbin/hbase-daemon.sh start masterbin/hbase-daemon.sh start regionserver

Use jps to view processes

If the above process is included, it will be started successfully.

Then go to the hdfs directory of hadoop and see that the hbase directory is already under the hdfs directory.
