Mike Fagan commented on ACCUMULO-2544:
--------------------------------------

This seams like a really odd way to submit a patch...
I would have though I should use git send-email

> The api for deleteRows specifies: Delete rows between (start, end] but the current implementation
for MockTableOperations.deleteRows is implemented as (start, end)
> Here is the failing test case
> public class TestDelete {
>   private static final String INSTANCE = "mock";
>   private static final String TABLE = "foo";
>   private static final String USER = "user";
>   private static final String PASS = "password";
>   private static final Authorizations AUTHS = new Authorizations();
>   @Test
>   public void testDelete() throws TableNotFoundException, AccumuloException,
>       AccumuloSecurityException, TableExistsException {
>     MockInstance mockAcc = new MockInstance(INSTANCE);
>     Connector conn = mockAcc.getConnector(USER, new PasswordToken(PASS));
>     conn.tableOperations().create(TABLE);
>     conn.securityOperations().grantTablePermission(USER, TABLE, TablePermission.READ);
>     conn.securityOperations().grantTablePermission(USER, TABLE, TablePermission.WRITE);
>     Mutation mut = new Mutation("2");
>     mut.put("colfam", "colqual", "value");
>     BatchWriter writer = conn.createBatchWriter(TABLE, new BatchWriterConfig());
>     writer.addMutation(mut);
>     Scanner scan = conn.createScanner(TABLE, AUTHS);
>     scan.setRange(new Range("2", "2"));
>     assertEquals(1, countRecords(scan));
>     
>     // this should delete (1,2] 
>     conn.tableOperations().deleteRows(TABLE, new Text("1"), new Text("2"));
>     scan = conn.createScanner(TABLE, AUTHS);
>     scan.setRange(new Range("2", "2"));
>     
>     // this will fail if row 2 exists
>     assertEquals(0, countRecords(scan));
>   }
>   private int countRecords(Scanner scan) {
>     int cnt = 0;
>     for (Entry<Key, Value> entry : scan) {
