> While trying to fix HBASE-13001, I realized that there is lot of html code repetition
in table.jsp which is making addition of new checks slightly difficult in the sense I will
have to:
> 1. Add the check at multiple places in the code
> Or 
> 2. Repeat the html code again for the new check 
> So I am proposing to re-factor table.jsp code such that the common html header/body is
loaded without any condition check and then we generate the condition specific html code 
> snapshot.jsp follows the same format as explained below:
> {noformat}
> Current implementation:
> ====================
> if( x ) {
>   title_x
>   common_html_header
>   common_html_body
>   x_specific_html_body
> } else {
>   title_y
>   common_html_header
>   common_html_body
>   y_specific_html_body
> }
> New Implementation:
> ==================
> if( x ) {
>   title_x
> } else {
>   title_y
> }
> common_html_header
> common_html_body
> if( x ) {
>   x_specific_html_body
> } else {
>   y_specific_html_body
> }
> {noformat}
