Core of this project is based on krejcmat/hadoop-docker images. Please check details on mentioned site. Dockerfile sources of this project extends Hadoop docker (krejcmat/hadoop-docker) images by few layers with HBase installation and configuration. As handler of HBase native Zookeeper is used. For large clusters is highly recomanded to use external Zookeeper management(not include).
######Version of products
| system | version |
|---|---|
| HBase | 1.2.4 |
Used versions of Hadoop and HBase are officially compatible - fully tested. As handler of HBase native Zookeeper is used. For large clusters is highly recomanded to use external Zookeeper management(not include).

###Usage ####1] Clone git repository
$ git clone https://github.com/krejcmat/hadoop-hbase-docker.git
$ cd hadoop-hbase-docker
####2] Get docker images Two options how to get images are available. By pulling images directly from Docker official repository or build from Dockerfiles and sources files(see Dockerfile in each hadoop-hbase-* directory). Builds on DockerHub are automatically created by pull trigger or GitHub trigger after update Dockerfiles. Triggers are setuped for tag:latest. Below is example of stable version krejcmat/hadoop-hbase-<>:0.1. Version krejcmat/hadoop-hbase-<>:latest is compiled on DockerHub from master branche on GitHub.
######a) Download from Docker hub
$ docker pull krejcmat/hadoop-hbase-master:latest
$ docker pull krejcmat/hadoop-hbase-slave:latest
######b)Build from sources(Dockerfiles) Firstly build Hadoop dockere images krejcmat/hadoop-docker. The first argument of the script for bulilds is must be folder with Dockerfile. Tag for sources is latest
$ ./build-image.sh hadoop-hbase-base
######Check images
$ docker images
krejcmat/hadoop-hbase-master latest 2f86a3daef76 48 minutes ago 1.091 GB
krejcmat/hadoop-hbase-slave latest ed119b77ecdf 53 minutes ago 1.091 GB
krejcmat/hadoop-hbase-base latest 00fd6c19004f 58 minutes ago 1.091 GB
####3] Initialize Hadoop (master and slaves) For starting Hadoop cluster see documentation of krejcmat/hadoop-docker.
If Hadoop is runnig go to next step.
####4] Initialize Hbase database and run Hbase shell ######Start HBase
$ cd ~
$ ./start-hbase.sh
(hbase(main):001:0>)
######Check status
(hbase(main):001:0>)$ status
2 servers, 0 dead, 1.0000 average load
######Example of creating table and adding some values
$ create 'album','label','image'
Now you have a table called album, with a label, and an image family. These families are “static” like the columns in the RDBMS world.
Add some data:
$ put 'album','label1','label:size','10'
$ put 'album','label1','label:color','255:255:255'
$ put 'album','label1','label:text','Family album'
$ put 'album','label1','image:name','holiday'
$ put 'album','label1','image:source','/tmp/pic1.jpg'
Print table album,label1.
$get 'album','label1'
COLUMN CELL
image:name timestamp=1454590694743, value=holiday
image:source timestamp=1454590759183, value=/tmp/pic1.jpg
label:color timestamp=1454590554725, value=255:255:255
label:size timestamp=1454590535642, value=10
label:text timestamp=1454590583786, value=Family album

####5] Control cluster from web UI ######Overview of UI web ports
| web ui | port |
|---|---|
| Hbase | 60010 |
######Access from parent computer of docker container Check IP addres in master container
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
link/ether 02:42:ac:11:00:02 brd ff:ff:ff:ff:ff:ff
inet 172.17.0.2/16 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::42:acff:fe11:2/64 scope link
valid_lft forever preferred_lft forever
so your IP address is 172.17.0.2
$ xdg-open http://172.17.0.2:60010/
######Direct access from container(not implemented) Used Linux distribution is installed without graphical UI. Easiest way is to use another Unix distribution by modifying Dockerfile of hadoop-hbase-dnsmasq and rebuild images. In this case start-container.sh script must be modified. On the line where the master container is created must add parameters for X forwarding.
