-----------------------------------
[[email protected]]
Since no split keys related APIs in HTableInterface I didn't add there. I will
raise a separate issue for adding all split key related APIs in HTableInterface
and work on it. Is it ok?
> truncate_preserve should get table split keys as it is instead of converting
> them to string type and then again to bytes

> If we take int,long or double bytes as split keys then we are not creating
> table with same split keys because converting them to strings directly and to
> bytes is giving different split keys, sometimes getting IllegalArgument
> exception because of same split keys(converted). Instead we can get split
> keys directly from HTable and pass them while creating table.

> splits = h_table.getRegionLocations().keys().map{|i| i.getStartKey}
