Ubuntu Install HBase

Download: http://mirror.bit.edu.cn/apache/hbase/stable/

Official Guide: http://abloz.com/hbase/book.html

Installation configuration:

Extract:

TAR-XZVF hbase-0.96.0-hadoop1-bin.tar.gz

Go to $hbase/lib and look at the related Hadoop package to see which version of Hadoop it is.

Only the installation of the pseudo-distributed hbase is logged here.

Configuration parameters, modify Hbase-site.xml:

Pseudo-distributed Startup:

Pseudo-distributed is HDFS-based, so you need to start HDFs first.

After you start hbase

SH start-hbase.sh

No unexpected error:

Enter Help, which lists the commands supported by the HBase shell

Shutdown is to close the HBase cluster and exit is to exit the HBase shell.

HBase Shell Practice

Build table

HBase (main):006:0> create ' test ', ' CF '

List all Tables

HBase (main):007:0> list
TABLE
Test
1 row (s) in 0.0440 seconds


= = ["Test"]

Inserting data

HBase (main):008:0> put ' test ', ' row1 ', ' cf:a ', ' value1 '
0 row (s) in 0.0750 seconds


HBase (main):009:0> put ' test ', ' row2 ', ' cf:b ', ' value2 '
0 row (s) in 0.0080 seconds


HBase (main):010:0> put ' test ', ' row3 ', ' cf:c ', ' value3 '
0 row (s) in 0.0060 seconds

Check Insert Condition

HBase (main):011:0> scan ' test '
ROW Column+cell
Row1 column=cf:a, timestamp=1386389158263, value=value1
Row2 column=cf:b, timestamp=1386389170821, value=value2
Row3 column=cf:c, timestamp=1386389185954, Value=value3
3 row (s) in 0.0450 seconds

Get Row

HBase (main):012:0> get ' test ', ' row2 '
COLUMN CELL
Cf:b timestamp=1386389170821, Value=value2
1 row (s) in 0.0140 seconds

drop table after disable

HBase (Main):013:0> disable ' test '
0 row (s) in 1.4220 seconds


HBase (Main):014:0> drop ' test '
0 row (s) in 0.2740 seconds


HBase (main):015:0> list
TABLE
0 row (s) in 0.0270 seconds
