> TestSafeModeWithStripedFile#testStripedFile0 fails randomly because:
> In below code they are restarting DN and even before DN registration happens to NN, block
report is triggered and following operation fails
>  i) Safemode safe block is counted (which is coming as 0 randomly , eventhough one block
is safe )
>  ii) Check for NN in safemode.
> {code}
>       cluster.restartDataNode(dnprops.remove(0));
>       cluster.triggerBlockReports();
>       assertEquals(1, NameNodeAdapter.getSafeModeSafeBlocks(nn));
> {code}
> {code}
>      dnProperty = dnprops.remove(0);
>     restartDN(dnProperty,nameNodeAddress);
>     assertFalse(nn.isInSafeMode());
> {code}
