> java.lang.NullPointerException: null
> 	at org.apache.hadoop.hdfs.server.blockmanagement.TestBlockManager.testBlockManagerMachinesArray(TestBlockManager.java:1202)

> The NPE suggests corruptStorageDataNode in the following code snippet could be null.
> {code}
> for(int i=0; i<corruptStorageDataNode.getStorageInfos().length; i++) {

> Looking at the code, the test does not wait for file replication to happen, which is
why corruptStorageDataNode (the DN of the second replica) is null.
