[jira] [Created] (ACCUMULO-309) MockBatchScanner is broken
MockBatchScanner is broken
--------------------------
Key: ACCUMULO-309
URL: https://issues.apache.org/jira/browse/ACCUMULO-309
Project: Accumulo
Issue Type: Bug
Affects Versions: 1.4.0
Reporter: John Vines
In my attempt to test a potential fix for ACCUMULO-175, I discovered the following code did not return any results-
{noformat}
public class TestRunningAgainstMock {
public static void main(String[] args) throws AccumuloException, AccumuloSecurityException, TableExistsException, TableNotFoundException,
InterruptedException
{
MockInstance mi = new MockInstance("test");
Connector conn = mi.getConnector("root", new byte[0]);
conn.tableOperations().create("testTable", true);
Mutation m = new Mutation("row");
m.put("cf", "cq", "val");
BatchWriter bw = conn.createBatchWriter("testTable", 500, 500, 1);
bw.addMutation(m);
bw.flush();
bw.close();
Scanner bs = conn.createBatchScanner("testTable", new Authorizations(), 1);
Iterator<Entry<Key,Value>> iter = bs.iterator();
if (!iter.hasNext())
System.out.println("No values");
while (iter.hasNext())
System.out.println(iter.next());
}
}{noformat}
Switching it to a regular scanner did work though.

[jira] [Resolved] (ACCUMULO-309) MockBatchScanner is broken

John Vines resolved ACCUMULO-309.
---------------------------------
Resolution: Fixed
Assignee: John Vines
Error was on my end, I never set the range. However, MockBatchScanner should more closely emulate the behavior of TabletServerBatchScanner, so I went ahead and changed it's setup behavior to error the same way the real batchScanner does.
