Hi,
It looks like the problem is that the initial value you're inserting in the
column is an int, while HTable#incrementColumnValue() expects a long.
Instead of:
> I enter data by :-
> theput.add(Bytes.toBytes("uid"),Bytes.toBytes("1"), 1301087829999L + t,
> Bytes.toBytes(10))
>
try:
theput.add(Bytes.toBytes("uid"),Bytes.toBytes("1"), 1301087829999L + t,
Bytes.toBytes(10L));
