HBase Tutorial

Learn How HBase Work in Simple Example

# HBase Shell startup
hbase shell

# get Hbase Shell commande list 
table_help

# show TABLES in HBase Shell
list

# if a TABLE exists in HBase
exists 'table_name'

# Hbase Shell shutdown
exit

Create HBase TABLE hiking :

The syntax to create TABLE :

# commande to create HBase TABLE with family columns  
CREATE 'table_name', 'family_column1','family_column2',....

The syntax to descibe TABLE :

# show HBase TABLE structure
DESCRIBE 'table_name'

hiking Table Structure :

  hiking(id, name, region, distance , Altitude, suiteHiking)

Divide 'hiking' TABLE on 2 family column :

  InfoHiking: name, region et suiteHiking
  InfoTechnique: distance et Altitude

commande :

# create table with 2 family columns
CREATE 'hiking', 'InfoHiking','InfoTechnique'

Write in 'hiking' TABLE :

The syntax to write in TABLE :

# write in TABLE 
put 'table_name', 'id', 'family_column:column', 'value'

example :

We will to write this informations in 'hiking' TABLE

Update TABLE :

Update the distance of the first hiking (55 instead of 35) :

put 'hiking', 1, 'InfoTechnique:distance', 55

Get From TABLE :

The syntax to get from TABLE :

# for a single line
get 'table_name', 'id'
get 'table_name', 'id', 'family'
get 'table_name', 'id', 'family:column'
get 'table_name', 'id', {COLUMN=>'family'}
get 'table_name', 'id', {COLUMN=>'family:column'}

# for a several line
1- scan 'table_name'
2- scan 'table_name', {COLUMN=>['family']}
3- scan 'table_name', {COLUMN=>['family:column']}

example:

get from TABLE hiking 4 :

get 'hiking', '4'

get InfoHiking of hiking 5.

get 'hiking', 5, 'InfoHiking'

Use FILTER :

Filters In Hbase Shell Tutorial

The syntax to filter DATA :

# for a single line
get 'table_name', 'id', {FILTER=>"filter"}

or :

# for a several line
scan 'table_name', {FILTER=>"filter"}

show the list of filters available in HBase :

show_filters

example :

get the distance of the hiking 'Murdjadu Mountain' :

scan 'hiking',{FILTER=>
	"SingleColumnValueFilter('InfoHiking', 'name', =,'binary:Montagne de Murdjadju')
	AND ColumnPrefixFilter ('distance')
	"}

or :

scan 'hiking',{FILTER=>
		"SingleColumnValueFilter('InfoHiking', 'name', =,'binary:Montagne de Murdjadju')
		AND QualifierFilter(=,'binary:distance')
	"}

get the distance of the hiking in the region of 'Tizi Ouzou' :

scan 'hiking',{FILTER=>
		"SingleColumnValueFilter('InfoHiking', 'region', =,'binary:Tizi Ouzou')
		AND QualifierFilter(=,'binary:distance') 
	"}
