Hello,
My problem seems to occur after a server restart. As a matter of fact,
if I clean the data, create a new keyspace and and its structure with
cqlsh, I can use the database correctly (both with cqlsh and a Java
application with Astyanax). If I stop the server and restart it, I have
my problem and then my requests don't work anymore (for example,
requests with where clause).
Thanks for your help!

Here is the definition of the related table CellMessage:
CREATE TABLE CellMessage (
id text PRIMARY KEY,
"type" text,
version text,
content text,
title text,
generated text,
date text
) WITH
comment='' AND
comparator=text AND
read_repair_chance=0.100000 AND

min_compaction_threshold=4 AND
max_compaction_threshold=32 AND
replicate_on_write='true' AND
compaction_strategy_class='SizeTieredCompactionStrategy' AND
compression_parameters:sstable_compression='SnappyCompressor';
CREATE INDEX cellmessage_version ON CellMessage (version);
Such errors occur for most tables I defined...
Thanks very much for your help!
