Description

The test TestDataNodeVolumeFailure#testUnderReplicationAfterVolFailure fails frequently in recent Jenkins buildings. The stack infos:

org.apache.hadoop.hdfs.server.datanode.TestDataNodeVolumeFailure.testUnderReplicationAfterVolFailure

java.lang.AssertionError: There is no under replicated block after volume failure
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.assertTrue(Assert.java:41)
	at org.apache.hadoop.hdfs.server.datanode.TestDataNodeVolumeFailure.testUnderReplicationAfterVolFailure(TestDataNodeVolumeFailure.java:419)

We would be better using GenericTestUtils.waitFor here to wait for the condition being satisfied.
