    @vrajat I am having problem getting this to work. It's like this is my 
setup but I wonder if you have any idea to fix this
    - HBase bin release from Apache Mirror hbase/hbase-1.0.2/
    - HBase running, hbase shell working
    - Built distribution for Zeppelin
    - set JAVA_HOME, start Zeppelin, enable hbase, set hbase.home in property
    
    When I ran this
    ```
    %hbase
    help
    ```
    
    I got this
    ```
    (NameError) undefined local variable or method `help' for main:Object
    ```
    
    and in the log
    ```
