>
> When a table has been created, initializing a new HTable object for that
> table works properly, as expected, but initializing a new HTable against a
> nonexistent table in the same context (a table exists), a
> NoServerForRegionException is thrown instead of TableNotFoundException, as
> would be expected.
> If there haven't been any tables created, initializing a new HTable object
> against 'nosuchTable' throws TableNotFoundException, as expected.
> Running the following TestCase exposes the issue on my machine.
> {code:title=TestHTable.java|borderStyle=solid}
> package org.apache.hadoop.hbase;
> import java.io.IOException;
> import org.apache.hadoop.io.Text;
> /**
> * Tests HTable
> */
> public class TestHTable extends HBaseClusterTestCase implements HConstants {
> public void testTableNotFoundExceptionWithoutAnyTables() {
> try {
> new HTable(conf, new Text("notATable"));
> fail("Should have thrown a TableNotFoundException");
> } catch (TableNotFoundException e) {
> // expected
> } catch (IOException e) {
> e.printStackTrace();
> fail("Should have thrown a TableNotFoundException instead of a " +
> e.getClass());
> }
> }

> public void testTableNotFoundExceptionWithATable() {
> try {
> HColumnDescriptor column =
> new HColumnDescriptor(COLUMN_FAMILY.toString());
> HBaseAdmin admin = new HBaseAdmin(conf);
> HTableDescriptor testTableADesc =
> new HTableDescriptor("table");
> testTableADesc.addFamily(column);
> admin.createTable(testTableADesc);
> // This should throw a TableNotFoundException, it has not been created
> new HTable(conf, new Text("notATable"));
>
> fail("Should have thrown a TableNotFoundException");
> } catch (TableNotFoundException e) {
> // expected
> } catch (IOException e) {
> e.printStackTrace();
> fail("Should have thrown a TableNotFoundException instead of a " +
