Description

`IgniteCache#clear` invocation are not transactional.
But, currently, Ignite allow to invoke `clear` inside transaction.
This lead to unexpected behavior and hides business logic errors.

We must disallow IgniteCache#clear call inside transaction.

/** */
@Test
public void testClearInTransction() {
    IgniteCache<Object, Object> cache = client.createCache(new CacheConfiguration<>("my-cache").setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL));
    cache.put(1, 1);
    try (Transaction tx = client.transactions().txStart(TransactionConcurrency.PESSIMISTIC, TransactionIsolation.READ_COMMITTED)) {
        cache.put(2, 2);
        cache.clear();
        tx.commit();
    }
    assertFalse(cache.containsKey(1));
    assertTrue(cache.containsKey(2));
}
