Count Columnfamily
Hey, i am new to HBase an NoSQL-Databases in general.
I hope you can help me with my question!

I created a litte Table like this:

create 'blog', 'post', 'comment'

And filled it with stuff like that:

put 'blog' ,'post1', 'post:title', 'Post1-Title'
put 'blog' ,'post1', 'post:content', 'This is a Post-Content'
put 'blog' ,'post1', 'post:date', '01.12.2012'
put 'blog' ,'post1', 'comment:date', '01.01.2013'
put 'blog' ,'post1', 'comment:content', 'This is a comment'
put 'blog' ,'post1', 'comment:date', '01.02.2013'
put 'blog' ,'post1', 'comment:content', 'This is a second comment'

put 'blog' ,'post2', 'post:title', 'Post2-Title'
put 'blog' ,'post2', 'post:content', 'This is another Post-Content.'
put 'blog' ,'post2', 'post:date', '23.10.2013'
put 'blog' ,'post2', 'comment:date', '01.02.2013'
put 'blog' ,'post2', 'comment:content', 'This is another comment'
With "scan 'blog', {VERSIONS => 2}" i can, of course, get the posts and the
comments.
And with "count blog" i get the Number of Post in the Blog.
My Problem is:

I want a List with the names of the Posts with the Number of Comments given
to it,
but i am not sure how to do this.

Thanks for any Help!
