---------------------------------

             Summary: Sleep in TestLazyPersistFiles should be put into a loop
                 Key: HDFS-14029
                 URL: https://issues.apache.org/jira/browse/HDFS-14029
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
            Reporter: Adam Antal


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.
{code:java}
    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());
{code}
