Description

TestLazyPersistFiles#testFileShouldNotDiscardedIfNNRestarted test should be improved.

The test sleeps for 6000 at once, it could at least sleep in a loop checking for the corrupt block to be reported.

    cluster.shutdownDataNodes();

    cluster.restartNameNodes();

    // wait for the redundancy monitor to mark the file as corrupt.
    Thread.sleep(2 * DFS_NAMENODE_REDUNDANCY_INTERVAL_SECONDS_DEFAULT * 1000);

    Long corruptBlkCount = (long) Iterators.size(cluster.getNameNode()
        .getNamesystem().getBlockManager().getCorruptReplicaBlockIterator());

Thanks knanasi for the suggestion.
