    Description

      TestDataNodeHotSwapVolumes#testRemoveVolumeBeingWritten fails occasionally in the following verification.

        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());
        704
