Subject Re: HBase use how much hdfs storage space

Hi Kun,

That will give you the HFile information only. One region can have multiple
HFiles. But you can also call this tool giving it the RegionName and not
the HFile. But at the end, that will still give you only the region size.
If you want to have the table size, then you will need to loop over all the
regions.
