    Description

      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

       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)

      eg:

      \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

      Simple patch is using binary string instead of normal string.
