the class TxCrossCacheMapOnInvalidTopologyTest method doTestCrossCacheTxMapOnInvalidTopology.

/**
 * Test scenario: cross-cache tx is started when node is left in the middle of rebalance, first cache is rebalanced
 * and second is partially rebalanced.
 *
 * First cache map request will trigger client compatible remap for pessimistic txs,
 * second cache map request should use new topology version.
 *
 * For optimistic tx remap is enforced if more than one mapping in transaction or all enlisted caches have compatible
 * assignments.
 *
 * Success: tx is finished on ideal topology version over all mapped nodes.
 *
 * @param concurrency Concurrency.
 * @param isolation Isolation.
