junit测试中，当无法连接hbase集群，使用PowerMock测试 mock hbase连接，mock类如下：

    /** 
    * QueryCanTask Tester. 
    * 
    * @author <Authors name> 
    * @since 12/18/2017
    * @version 1.0 
    */
    @RunWith(PowerMockRunner.class)
    @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class) //委派给SpringJUnit4ClassRunner
    @PowerMockIgnore("javax.management.*")
    @PrepareForTest({ HBaseConfiguration.class, ConnectionFactory.class, Configuration.class,
        Table.class, ResultScanner.class})
    //@SuppressStaticInitializationFor("com.xxxx")//阻止静态代码块运行
@ContextConfiguration(locations = { "classpath:applicationContext/*.xml" })
public class QueryCanTaskTest
{  
    private Configuration configuration = PowerMockito.mock(Configuration.class);

    private Connection connection = PowerMockito.mock(Connection.class);

    private Table table = PowerMockito.mock(Table.class);

    @Before
    public void before() throws Exception
    {
        //初始化静态变量
        new SystemCfgConstants();
        PowerMockito.when(HBaseConfiguration.create()).thenReturn(configuration);
        PowerMockito.when(ConnectionFactory.createConnection(configuration)).thenReturn(connection);
        PowerMockito.when(Connections.getTable(TableInfo.TABLE)).thenReturn(table);
        PowerMockito.when(Connections.getTable(RawDataTable.tableName)).thenReturn(table);
       PowerMockito.when(table.getScanner(scan)).thenReturn(yourest);
    }

    @After
    public void after() throws Exception
    {
    }

    /**
    * 
    * Method: 
    * 
    */
    @Test
    public void testQueryList() throws Exception
    {
        //TODO test
    }

}

在hbase-site.xml添加如下配置，跳过版本检查

<property>
        <name>hbase.defaults.for.version.skip</name>
        <value>true</value>
        <description>
            Set to true to skip the 'hbase.defaults.for.version' check.
            Setting this to true can be useful in contexts other than
            the other side of a maven generation; i.e. running in an
            ide.  You'll want to set this boolean to true to avoid
            seeing the RuntimException complaint: "hbase-default.xml file
            seems to be for and old version of HBase (0.92.1), this
            version is X.X.X-SNAPSHOT"
        </description>
    </property>
