Jim Kellerman commented on HADOOP-1391:
---------------------------------------
Bigtable applies attributes on a per column basis. For example, the number of
versions kept for a column family, access control, compression are all per
column family attributes. Currently max versions is a per table attribute in
HBase. Since we are going to be modifying table and column descriptions for
this set of enhancements, we should take this opportunity to make max versions
a per column attribute as well.
