Number of tables in HBase.

Hello,

I know that a table should have a content number of CFs. How about the
number of tables in the same HBase cluster? it should be okay to have
dozens of tables or it's thought to have just a few number of tables?

Having dozens of tables in a multi-tenant cluster is okay. 

How many regions on average would each table have ?

The total number of regions should have higher weight in your planning compared to the total number of tables. 

Cheers

Sorry, I mean just few column families,, 1 to 3 column families. But I
don't know if it's a good idea to have too many tables in HBase.
