             Summary: Cannot create splits with MSBit set in MSByte via API 
                 Key: ACCUMULO-2437
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2437
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.5.1
            Reporter: Aaron Kimball


I cannot create a table with 256 evenly-sliced splits using the API. I believe due to the fact that Text can only hold valid Unicode characters, the following only generates 129 splits:

{code}
    TableOperations tableOps = connector.tableOperations();
    TreeSet<Text> splits = new TreeSet<Text>();
    for (int i = 0; i < 256; i++) { 
      byte[] bytes = { (byte) i };
      String theStr = new String(bytes);
      splits.add(new Text(theStr));
    } 
    tableOps.addSplits(TABLE_NAME, splits);
{code}

Using {{getsplits}} in the shell, I see the highest split be 0x7F; while we can use byte values 0x80 through 0xFF as leading bytes in row keys, the use of {{Text}} in the {{addSplits()}} method makes these invalid strings to split on.
