Re: Why the Range not find the data

[Josh Elser]

The key

    0 cf0:cq0
is greater than

    0 cf0:

(with an empty column qualifier).

This is why your first range finds nothing. Inclusivity is based on the 
entire key, not just the components of the key you provided.

In my accumulo cluster ,the table has this data:
0 cf0:cq0 [] v0
1 cf1:cq1 [] v1

then I use scan to find it like this:

ranges.add(newRange(newKey(newText("0"), newText("cf0")), true,
                      newKey(newText("0"), newText("cf0")), true));

but it tell me #results=0.

If i code like this:

ranges.add(newRange(newKey(newText("0"), newText("cf0")), true,
                      newKey(newText("0"), newText("cf00")), true));

it works OK.


api show me if I set true ,it will include the start and end key.Why I
can not find the data ?

Thanks.
