> When we run datanode from the machine with big disk volume, it's found du operations
from org.apache.hadoop.fs.DU's DURefreshThread cost lots of disk performance.
> As we use the whole disk for hdfs storage, it is possible calculate volume usage via
"df" command. Is it necessary adding the "df" option for usage calculation in hdfs (org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.BlockPoolSlice)?
