Installing Hbase on Ubuntu

I've been playing with this more than expected so this is to save you from all the troubles I was in.
Here goes:
1) Download desired (stable) Hbase version
2) Copy entire folder to your machine. I used folder /usr/lib
3) Save path into .profile.
export HBASE_HOME=/usr/lib/hbase-0.20.3
export PATH=$HBASE_HOME/bin:$PATH"
4) Install Java, set paths and home if necessary
5) Edit conf/hbase-env.sh and define JAVA_HOME
6) Change ownership of hbase-0.20.3 folder. Log files need write permissions!!
7) Install SSH if necessary
sudo apt-get install openssh-server openssh-client
8) Setup SSH without password
ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
9) Make sure that you can log into localhost without a password
10) Run ./start-hbase.sh from bin folder

In case of troubles, check this post:

    Hi, thanks for this post :)

    I want to setup HBase in standalone mode on local filesystem.
    I want to use local file system so I guess no need to install hadoop
    and zookeeper.
    I followed the instructions from http://hbase.apache.org/book/quickstart.html
    i didnt set hbase.rootdir in conf/hbase-site.xml as it will use default /tmp

    I am using Kubuntu 12.10 and and
    JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk as java 1.6 is required.

    HBase shell is running fine but I am unable to create table
    I am getting error

    hbase(main):001:0> create 'test', 'cf'

    ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

    Here is some help for this command:
    Create table; pass table name, a dictionary of specifications per
    column family, and optionally a dictionary of table configuration.
    Dictionaries are described below in the GENERAL NOTES section.
    Examples:

    hbase> create 't1', {NAME => 'f1', VERSIONS => 5}
    hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}
    hbase> # The above in shorthand would be the following:
    hbase> create 't1', 'f1', 'f2', 'f3'
    hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000,
    BLOCKCACHE => true}
    hbase> create 't1', 'f1', {SPLITS => ['10', '20', '30', '40']}
    hbase> create 't1', 'f1', {SPLITS_FILE => 'splits.txt'}
    hbase> # Optionally pre-split the table into NUMREGIONS, using
    hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
    hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit'}


    hbase(main):002:0>

    can you tell me where I am wrong?

    It seems Hbase didn't start. Do you use start-hbase.sh? What do your logs say?
