Issue Type: Bug
Components: hdfs
Affects Versions: 3.0.0-alpha2

TestDataNodeHotSwapVolumes#testRemoveVolumeBeingWritten fails occasionally in
the following verification.
{code}
700 // If an IOException thrown from BlockReceiver#run, it triggers
701 // DataNode#checkDiskError(). So we can test whether checkDiskError()
is called,
702 // to see whether there is IOException in BlockReceiver#run().
703 assertEquals(lastTimeDiskErrorCheck, dn.getLastDiskErrorCheck());
