I created a table by

create 'tablename', 'columnfamily1'

Now is it possible to add another column family 'columnfamily2'? What is the method?

It seems 

alter 'tablename', 'columnfamily2'

does the trick. One may, disable 'tablename' first. However, it works fine even if enabled.

hbase(main):015:0> alter 'tablename', {NAME=> 'columnfamily2'}
Updating all regions with the new schema...
0/1 regions updated.
1/1 regions updated.
Done.
