> Is it possible to use "df" to calculate the dfs usage instead of "du"

> 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)?
