Description

We've seen this test fail occasionally with an error like the following:

java.lang.AssertionError
	at org.apache.hadoop.hdfs.server.datanode.BPServiceActor.offerService(BPServiceActor.java:510)
	at org.apache.hadoop.hdfs.server.datanode.BPServiceActor.run(BPServiceActor.java:695)
	at java.lang.Thread.run(Thread.java:745)

This assertion fires when the heartbeat response is null
