Apache Hbase installation

I am trying to install Hbase(hbase-0.94.8) in ubuntu 12.04 enviroment.

I followed exactly the same steps given in this page

http://hbase.apache.org/book/quickstart.html

I am able to start Hbase and enter into shell but when i type "create 'test', 'cf'" from shell the following ERRORS were thrown

hbase(main):001:0> create 'test', 'cf'
13/06/11 13:01:40 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.
13/06/11 13:01:41 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.
13/06/11 13:01:42 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

13/06/11 13:01:50 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.
13/06/11 13:01:54 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

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'}

Please anyone explain me what is issue with this installation.

the HMaster has to be started. You can do that using webUI.Use cloudera manager to webUi to start the hbase master. Then it will work fine

i got the same error to correct it go to hbase-site.xml in conf folder and remove the comments before and after property tag(<!-- -->).

This is my hbase.site.xml file you can compare it with yours. Hope this helps.
