示例1: testModifyTable
import org.apache.hadoop.hbase.HTableDescriptor; //导入方法依赖的package包/类
@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());
