Description:
{{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.
{code:bash}
