CQL COUNT Not Accurate?

[Hefeng Yuan]

Hi,

I just noticed that the count(*) in CQL seems to be having wrong answer, when I 
have only one row, the count(*) returns two.

Below are the commands I tried:

cqlsh> SELECT COUNT(*) FROM UserProfile USING CONSISTENCY QUORUM WHERE KEY IN 
('00D760DB1730482D81BC6845F875A97D');
(2,)
cqlsh> select * from UserProfile where key = '00D760DB1730482D81BC6845F875A97D';
u'00D760DB1730482D81BC6845F875A97D' | 
u'ScreenName','3D5C78CAE2E143FBBD1F539A8496D472'

Is this a known bug? Or I did something wrong?

Thanks,
Hefeng
