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());
