Can read/write to Cassandra w/ Talend - can't SELECT w/ Csndra GUI ???

I'm using TOS 5.6.2, and I'm writing to a Cassandra cluster DB on my laptop for a POC ( Cassandra version 2.1.6 ). I have no problems writing to the Cassandra DB with Talend, and reading from the DB with Talend ( very, very simple read and right Talend jobs, opening a connection to Cassandra and writing, and spitting loaded data back with tLogRow ). 
However, when I attempt to do something simple like this on my Cassandra GUI, after I've loaded some data:
SELECT * FROM keyspace.table
nothing comes back....ever. I would think this must be a fairly simple operation, as with pretty much every other DB I've dealt with, so I'm thinking I must be doing something fundamentally wrong at this point.
I'm new with Cassandra and Talend, and I attempted search for a solution on this forum..my apologies if this issue has been covered previously.
Thank you in advance for any input you might have on my issue

Hi deandeloach,
Do you mean there is no row loaded into Cassandra DB during the ETL processing(writing to a Cassandra cluster DB )?
Have you already checked that is there any loaded data in your keyspace.table? Would you mind uploading your job design screenshots into forum?
tinputxxx-->tCassandraoutput
tCassandraInput-->tLogrow

Best regards
Sabrina

 Thank you for your response Sabrina.  Here's some additional info regarding my issue ( all of this is taking place on my laptop, as a simple POC - except for the MS SQL*Server source ).  Also including the DDL for my Cassandra table:
CREATE TABLE hr.person (
 personid int,
 charitymemo text,
 city text,
 fhindex int,
 firstname text,
 lastname text,
 middlename text,
 PRIMARY KEY (personid)
);
this inserts a record no problem in the Cassandra GUI, that can be SELECT'd right back:
INSERT INTO hr.person (
 personid ,
 charitymemo ,
 city ,
 fhindex ,
 firstname ,
 lastname ,
 middlename
)
VALUES(
1,
'TEST',
'TEST',
1,
'TEST',
'TEST',
'TEST'
)
maybe I'm not SELECT'ing against Cassandra improperly(?)/the data is stored somewhere else in the DB...?  When I use my simple Talend poc job, the tLogRow component will output what I've loaded - no problem - and when I go into the Cassandra GUI and TRUNCATE the test table, then no data is available from the tLogRow component output - which makes perfect sense.  So, I know that Talend is writing to the Cassandra DB - somewhere, at some point. But even when the tLogRow component outputs loaded data, it can't be SELECT'd...?????

Re: Can read/write to Cassandra w/ Talend - can't SELECT w/ Csndra GUI ???

you know, Sabrina, I figured out what the problem is.  My problem had to do with my laptop-installed/local Cassandra instance.  I installed a Cassandra cluster on AWS, and it worked just fine.
Thank you just the same for the responses and help, much appreciated....
