You do it by simply inserting a cell with the same key as the one you
want to update, e.g.
if you have a cell
ROW_KEY_1 column_family:qualifier VALUE_1
and you want it to be VERY_LONG_VALUE_1 you do it by running this command
hypertable> insert into table dummy_table values ("ROW_KEY_1",
"column_family:qualifier", "VERY_LONG_VALUE_1");
this will also retain the previous version unless you have a limit on
the number of versions you want to keep in your table. The newer cells
sort before the older ones so it's going to be the first one to be
retrieved.
Let's just hope I am not wrong :-)
