> Binary region boundaries become wrong during
> converting byte array to normal string, and back to byte array in
> truncate_preserve of admin.rb, which makes the truncation of table failed.
> See: truncate_preserve method in admin.rb
> {code}
> splits = h_table.getRegionLocations().keys().map{|i|
> Bytes.toString(i.getStartKey)}.delete_if{|k| k == ""}.to_java :String
> splits = org.apache.hadoop.hbase.util.Bytes.toByteArrays(splits)
> {code}
> eg:
> {code}
> \xFA\x00\x00\x00\x00\x00\x00\x00 -> \xEF\xBF\xBD\x00\x00\x00\x00\x00\x00\x00
> \xFC\x00\x00\x00\x00\x00\x00\x00 -> \xEF\xBF\xBD\x00\x00\x00\x00\x00\x00\x00
