> When performing an "alter" on multiple column families in a table, then shell will perform
a separate {{Admin.modifyColumn()}} call for each column family being modified, with all of
the table regions being bulk-reopened each time.  It would be much better to simply apply
all the changes to the table descriptor, then do a single call to {{Admin.modifyTable()}}.
