Example 3 with MaintenanceRegistry

use of org.apache.ignite.maintenance.MaintenanceRegistry in project ignite by apache.

the class IgnitePdsDefragmentationTest method createMaintenanceRecord.

/**
 */
protected void createMaintenanceRecord(String... cacheNames) throws IgniteCheckedException {
    IgniteEx grid = grid(0);

}

Example 4 with MaintenanceRegistry

use of org.apache.ignite.maintenance.MaintenanceRegistry in project ignite by apache.

the class LocalWalModeChangeDuringRebalancingSelfTest method testPdsWithBrokenBinaryConsistencyIsClearedAfterRestartWithDisabledWal.

/**
 * Test is opposite to {@link #testConsistentPdsIsNotClearedAfterRestartWithDisabledWal()}
 *
 * <p>
 * Test scenario:
 * <ol>
 *      <li>
 *          Two server nodes are started, cluster is activated, baseline is set. 2500 keys are put into cache.
 *      </li>
 *      <li>
 *          Checkpoint is started and finished on both nodes.
 *      </li>
 *      <li>
 *          Node n1 is stopped, another 2500 keys are put into the same cache.
 *      </li>
 *      <li>
 *          Node n1 is started back so rebalancing is triggered from n0 to n1. WAL is turned off on n1 automatically.
 *      </li>
 *      <li>
 *          Both nodes are stopped without checkpoint.
 *      </li>
 *      <li>
 *          CP END marker for the first checkpoint is removed on node n1 so node will think it crushed during checkpoint
 *          on the next restart.
 *      </li>
 *      <li>
 *          Node n1 fails to start as it sees potentially corrupted files of one cache. Manual action is required.
 *      </li>
 *      <li>
 *          Cache files are cleaned up manually on node n1 and it starts successfully.
 *      </li>
 * </ol>
 * </p>
 *
 * @throws Exception If failed.
