Examples with HCatDatabase org.apache.hive.hcatalog.api.HCatDatabase used on opensource projects

Example 1 with HCatDatabase

use of org.apache.hive.hcatalog.api.HCatDatabase in project hive by apache.

the class TestCommands method testDropDatabaseCommand.

@Test
public void testDropDatabaseCommand() throws HCatException, CommandNeedRetryException {
    String dbName = "cmd_testdb";
    int evid = 999;
    Command testCmd = new DropDatabaseCommand(dbName, evid);
    assertEquals(evid, testCmd.getEventId());
    assertEquals(1, testCmd.get().size());
    assertEquals(true, testCmd.isRetriable());
    assertEquals(false, testCmd.isUndoable());
    CommandTestUtils.testCommandSerialization(testCmd);
    client.dropDatabase(dbName, true, HCatClient.DropDBMode.CASCADE);
    client.createDatabase(HCatCreateDBDesc.create(dbName).ifNotExists(false).build());
    HCatDatabase db = client.getDatabase(dbName);
    assertNotNull(db);
    LOG.info("About to run :" + testCmd.get().get(0));
    driver.run(testCmd.get().get(0));
    Exception onfe = null;
    try {
        HCatDatabase db_del = client.getDatabase(dbName);
    } catch (Exception e) {
        onfe = e;
    }
    assertNotNull(onfe);
    assertTrue(onfe instanceof ObjectNotFoundException);
}

Example 2 with HCatDatabase

use of org.apache.hive.hcatalog.api.HCatDatabase in project hive by apache.

the class TestCommands method testNoopReplEximCommands.

@Test

    // import repl noop dump, no error
    int evid = 333;

    ImportCommand noopImportCmd = new ImportCommand(dbName, tableName, null, exportLocation, false, evid);
    LOG.info("About to run :" + noopImportCmd.get().get(0));
    CommandProcessorResponse ret2 = driver.run(noopImportCmd.get().get(0));
    assertEquals(ret2.getResponseCode() + ":" + ret2.getErrorMessage(), null, ret2.getException());
    Exception onfe = null;
