Install HBase

Successfully installed and ran HBase in full distributed mode on three nodes.

Hadoop 1.04

HBase 0.94.11

Check hduser OK.

Check SSH OK.

Check /etc/hosts setup OK.

1. Download hbase-x.y.z.tar.gz (x.y.z is the version number)

2. Extract the gz file and move the folder to /usr/local (or whatever proper location). Set hduser (or whatever user for running hbase) the owner of the folder

tar xzf hbase-x.y.z.tar.gz

sudo mv hbase-x.y.z /usr/local/hbase

chown -R hduser:hadoop /usr/local/hbase

3. Set JAVA_HOME and HADOOP_CONF_DIR in /usr/local/hbase/conf/hbase-env.sh.

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk

export HADOOP_CONF_DIR=/usr/local/hadoop/conf

Set HBASE_HOME in .bashrc

export HBASE_HOME=/usr/local/hbase

export PATH=$PATH:$HBASE_HOME/bin

4. Configure /hbase/conf/hbase-site.xml.

<name>hbase.rootdir</name>

<value>hdfs://master:54310/hbase</value>

</property>

<name>hbase.cluster.distributed</name>

</property>

<name>hbase.zookeeper.property.dataDIR</name>

<value>/urs/local/hbase/zookeeper</value>

</property>

<name>hbase.zookeeper.quorum</name>

<value>master, slave, slave2</value>

<description>1, 3, 5, 7 ... odd number of nodes</description>

</property>

</configuratioin>

5. Configure /hbase/conf/regionservers

master

slave

slave2

...

6. Copy /usr/local/hbase folder to all slave nodes.

6.1 zip the folder and transfer to slave & slave 2

tar czf hbase_configured.tar.gz hbase

scp hbase_configured.tar.gz hduser@slave:hbase_configured.tar.gz

6.2 unzip and configure from slave & slave2

ssh slave

tar xzf hbase_configured.tar.gz

sudo mv hbase /usr/local/hbase

chown -R hduser:hadoop /usr/local/hbase

7. Start hbase

hduser@ubuntu:/usr/local/hbase/bin$ ./start-hbase.sh

slave: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-hduser-zookeeper-ubuntu.out

slave2: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-hduser-zookeeper-ubuntu.out

master: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-hduser-zookeeper-ubuntu.out

starting master, logging to /usr/local/hbase/logs/hbase-hduser-master-ubuntu.out

master: starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-hduser-regionserver-ubuntu.out

slave: starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-hduser-regionserver-ubuntu.out

slave2: starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-hduser-regionserver-ubuntu.out

8. Check HBase web UI. The following URL should list all the attributes.

http://master:60010/

9. Start hbase shell

/hbase/bin/hbase shell

10. Test from the shell. List all tables. This should return 0 rows for the first time. If any error pops up the setup was not successful.

>list

8. Create a table 'test' with a column family called 'data'

>create 'test','data'

9. Insert test data into the table.

>put 'test', 'row1', 'data:column1', 'value1'

>put 'test', 'row2', 'data:column2', 'value2'

>put 'test', 'row1', 'data:column1', 'value3'

>put 'test', 'row2', 'data:column2', 'value4'

10. Show data in the table

> scan 'test'

ROW COLUMN+CELL

row1 column=data:column1, timestamp=1379360926325, value=value1

row1 column=data:column2, timestamp=1379360943922, value=value2

row2 column=data:column1, timestamp=1379360958865, value=value3

row2 column=data:column2, timestamp=1379360965475, value=value4

11. Get data from table

>get 'test', 'row1'

>get 'test', 'row1', 'data:column1'

>exit

12. Stop Hbase

/usr/local/hbase/bin/stop-hbase.sh
