示例1: testShouldFailOnlineSchemaUpdateIfOnlineSchemaIsNotEnabled

import org.apache.hadoop.hbase.HTableDescriptor; //導入方法依賴的package包/類
@Test (timeout=300000)
public void testShouldFailOnlineSchemaUpdateIfOnlineSchemaIsNotEnabled()
    throws Exception {
  final TableName tableName = TableName.valueOf("changeTableSchemaOnlineFailure");
  TEST_UTIL.getMiniHBaseCluster().getMaster().getConfiguration().setBoolean(
      "hbase.online.schema.update.enable", false);
  HTableDescriptor[] tables = admin.listTables();
  int numTables = tables.length;
  TEST_UTIL.createTable(tableName, HConstants.CATALOG_FAMILY).close();
  tables = this.admin.listTables();
  assertEquals(numTables + 1, tables.length);

  // FIRST, do htabledescriptor changes.
  HTableDescriptor htd = this.admin.getTableDescriptor(tableName);
  // Make a copy and assert copy is good.
  HTableDescriptor copy = new HTableDescriptor(htd);
  assertTrue(htd.equals(copy));
  // Now amend the copy. Introduce differences.
  long newFlushSize = htd.getMemStoreFlushSize() / 2;
  if (newFlushSize <=0) {
    newFlushSize = HTableDescriptor.DEFAULT_MEMSTORE_FLUSH_SIZE / 2;
  }
  copy.setMemStoreFlushSize(newFlushSize);
  final String key = "anyoldkey";
  assertTrue(htd.getValue(key) == null);
  copy.setValue(key, key);
  boolean expectedException = false;
  try {
    admin.modifyTable(tableName, copy);
  } catch (TableNotDisabledException re) {
    expectedException = true;
  }
  assertTrue("Online schema update should not happen.", expectedException);

  // Reset the value for the other tests
  TEST_UTIL.getMiniHBaseCluster().getMaster().getConfiguration().setBoolean(
      "hbase.online.schema.update.enable", true);
}

示例2: testModifyTable

import org.apache.hadoop.hbase.HTableDescriptor; //導入方法依賴的package包/類
@Test(timeout=60000)
public void testModifyTable() throws Exception {
  final TableName tableName = TableName.valueOf("testModifyTable");
  final ProcedureExecutor<MasterProcedureEnv> procExec = getMasterProcedureExecutor();

  MasterProcedureTestingUtility.createTable(procExec, tableName, null, "cf");
  UTIL.getHBaseAdmin().disableTable(tableName);

  // Modify the table descriptor
  HTableDescriptor htd = new HTableDescriptor(UTIL.getHBaseAdmin().getTableDescriptor(tableName));

  // Test 1: Modify 1 property
  long newMaxFileSize = htd.getMaxFileSize() * 2;
  htd.setMaxFileSize(newMaxFileSize);
  htd.setRegionReplication(3);

  long procId1 = ProcedureTestingUtility.submitAndWait(
      procExec, new ModifyTableProcedure(procExec.getEnvironment(), htd));
  ProcedureTestingUtility.assertProcNotFailed(procExec.getResult(procId1));

  HTableDescriptor currentHtd = UTIL.getHBaseAdmin().getTableDescriptor(tableName);
  assertEquals(newMaxFileSize, currentHtd.getMaxFileSize());

  // Test 2: Modify multiple properties
  boolean newReadOnlyOption = htd.isReadOnly() ? false : true;
  long newMemStoreFlushSize = htd.getMemStoreFlushSize() * 2;
  htd.setReadOnly(newReadOnlyOption);
  htd.setMemStoreFlushSize(newMemStoreFlushSize);

  long procId2 = ProcedureTestingUtility.submitAndWait(
      procExec, new ModifyTableProcedure(procExec.getEnvironment(), htd));
  ProcedureTestingUtility.assertProcNotFailed(procExec.getResult(procId2));

  currentHtd = UTIL.getHBaseAdmin().getTableDescriptor(tableName);
  assertEquals(newReadOnlyOption, currentHtd.isReadOnly());
  assertEquals(newMemStoreFlushSize, currentHtd.getMemStoreFlushSize());
}
