> Incorrect boundry matching for MockTableOperations.deleteRows
> -------------------------------------------------------------
>
> Key: ACCUMULO-2544
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2544
> Project: Accumulo
> Issue Type: Bug
> Components: test
> Affects Versions: 1.6.1
> Environment: Mac OS Mavericks; java 7
> Reporter: Mike Fagan
>
> 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) {
> cnt++;
> }
> scan.close();
> return cnt;
> }
> }
