Unit test fails on Windows: TestDatanodeBlockScanner

I see this assertion:
junit.framework.AssertionFailedError
at org.apache.hadoop.dfs.TestDatanodeBlockScanner.testBlockCorruptionPolicy(TestDatanodeBlockScanner.java:201)

and this in the standard error:

    Attachment: HADOOP-3396-1.patch

    This test was failing sporadically when run in a loop multiple times even on LINUX. The problem seemed to be the way block reports and bad block reports sent by Datanode to the Namenode. When a cluster (namenode and datanode) is started, it may sometimes happen that BlockScanner Thread could send a report about corrupt block even before block report is sent by DataNode to NameNode. Now, NameNode would have an entry in corruptReplicasMap about a block which is not in BlocksMap yet. At this point of time, if we invoke getBlockLocation, we hit ArrayIndexOutOfBound exception becuase we have a case where corruptReplicas is more than actual Replicas!

    This patch adds a check to FSNamesystem to make sure we do not insert corrupt replica into corruptRepliasMap if there is not Block in blocks map yet. We log it and ignore it. The patch also changes few things. Instead of restarting the whole cluster, we restart only the DataNode. Added few more checks to loop until we get correct values of replicas when asked for via getBlockLocations.

    I ran this test which was failing 25 times in a loop and it succeeds both on LINUX and WINDOWS
