Hi,
Add this import:
import org.apache.hadoop.hbase.HServerLoad;
And change names of classes:
ServerLoad -> HServerLoad
RegionLoad -> HServerLoad.RegionLoad

Hi Lucas
As you said that RegionSizeCalculator is developed on top of 0.94, the
class has interdependencies vig
import org.apache.hadoop.hbase.RegionLoad;
import org.apache.hadoop.hbase.ServerLoad;
unable to find these classes in 0.94.X
are these classes available in 0.94 under some other package,

Hi,
I am hbase newbie, maybe there is simpler solution but this will work. I
tried estimating size using HDFS but it is not best solution(see link [1]);
You dont need to work with TableSplits., look at class
org.apache.hadoop.hbase.util.RegionSizeCalculator.
It can do what you need. Create instance of this class, than call method
getRegionSizeMap() and sum all values in map. Note that the size contains
only storeFile sizes, not memStore sizes.
If you need customize behaviour of this class, just copy the code and
change it.
This class will be in version 0.98 but it was developed on 0.94 - it will
work but you will have to change some java imports.

Hi Lukas
the table split constructor expects startRow, endRow and location we won't
be having info about any of these.
Moreover we require table size as a whole, not split size.
We will use the table size to look for a threshold breach in metadata
table, if breached we have to trigger a delete operation on to the
table(of
which threshold is breached) to delete LRU records until table size is
within limit (~ 50-60Gb)

Hi
The requirement is to get the hbase table size (using API) and have to
save this size for each table in a metadata table .
i tried hdfs command to check table size but need api method (if
available)
Hadoop fs -du -h hdfs://
Thanks
