Ignite Cassandra cache configuration - CodecNotFoundException - caching

Question

I am trying to configure Cassandra as a persistent store for an Apache Ignite 2.0 cache. As a test, I am trying to map key-value pairs to this simple Cassandra table:
CREATE TABLE ignite.cache_test(
key text PRIMARY KEY,
value int)
That's the associated persistence configuration xml I am using:
<persistence keyspace="ignite" table="cache_test" ttl="86400">
<keyspaceOptions>
REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor' : 1}
AND DURABLE_WRITES = true
</keyspaceOptions>
<tableOptions>
comment = 'Cache test'
AND read_repair_chance = 0.2
</tableOptions>
<keyPersistence class="java.lang.String" strategy="PRIMITIVE" column="key" />
<valuePersistence class="java.lang.Integer" strategy="PRIMITIVE" column="value" />
</persistence>
When I try to put elements in the cache using the Ignite REST interface I get:
com.datastax.driver.core.exceptions.CodecNotFoundException: Codec not found for requested operation: [int <-> java.lang.String]
as if I am trying to map int to String type. I am sure it is a silly configuration error, but I tried several combinations with no success.
For completeness, that's the http call I am sending:
http://localhost:8080/ignite?cmd=put&key=testkey&val=1&cacheName=cache1
Thank you all for the help

Change the type of value to text
So the table schema :
CREATE TABLE ignite.cache_test(
key text PRIMARY KEY,
value text
);
And the configuration :
<persistence keyspace="ignite" table="cache_test" ttl="86400">
<keyspaceOptions>
REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor' : 1}
AND DURABLE_WRITES = true
</keyspaceOptions>
<tableOptions>
comment = 'Cache test'
AND read_repair_chance = 0.2
</tableOptions>
<keyPersistence class="java.lang.String" strategy="PRIMITIVE" column="key" />
<valuePersistence class="java.lang.String" strategy="PRIMITIVE" column="value" />
</persistence>
