> There seems to be some UT regressions after HDFS-11519, such as
> * TestDataNodeVolumeFailureToleration
> * TestDataNodeVolumeFailureReporting
> * TestDiskBalancerCommand
> * TestBlockStatsMXBean
> * TestDataNodeVolumeMetrics
> * TestDFSAdmin
> * TestDataNodeHotSwapVolumes
> * TestDataNodeVolumeFailure
> these tests set up datanode data dir by some hard coded names, such as 
> {code}
>   new File(cluster.getDataDirectory(), "data1");
> {code}
> this no longer works since HDFS-11519 changes the pattern from
> {code}
> /data/data<2*dnIndex + 1>
> /data/data<2*dnIndex + 2>
> ...
> {code}
> to 
> {code}
> /data/dn0_data0
> /data/dn0_data1
> /data/dn1_data0
> /data/dn1_data1
> ...
> {code}
