> {{TestBlockStatsMXBean#testStorageTypeStatsWhenStorageFailed}} loops three
> times to restart Datanodes. However, the code restart the DN-0 three times.
> As a result, the JUnit does not really execute the scenario it was supposed
> to.
> {code:java}
> DataNodeTestUtils.restoreDataDirFromFailure(dn1ArcVol1);
> DataNodeTestUtils.restoreDataDirFromFailure(dn2ArcVol1);
> DataNodeTestUtils.restoreDataDirFromFailure(dn3ArcVol1);
> for (int i = 0; i < 3; i++) {
> cluster.restartDataNode(0, true);
> }
> // wait for heartbeat
> Thread.sleep(6000);
> storageTypeStatsMap = cluster.getNamesystem().getBlockManager()
> .getStorageTypeStats();
> storageTypeStats = storageTypeStatsMap.get(StorageType.RAM_DISK);
> assertEquals(6, storageTypeStats.getNodesInService());
> {code}
> When I changed the loop inner block to {{cluster.restartDataNode(i, true)}},
> the test did not pass with the stack trace below. I suspect that one of the
> datanodes does not start properly after calling restart.
