sql：

        tEnv.executeSql("DROP TABLE IF EXISTS ywb_source");
        tEnv.executeSql(
                "CREATE TABLE ywb_source (\n" +
                        " rowkey STRING,\n" +
                        " info1 ROW<name STRING>,\n" +
                        " info2 ROW<age STRING>,\n" +
                        " PRIMARY KEY (rowkey) NOT ENFORCED\n" +
                        ") WITH (\n" +
                        " 'connector' = 'pa-hbase',\n" +
                        " 'table-name' = 'ywb_t1',\n" +
                        " 'zookeeper.quorum' = '10.100.2.191:2181'\n" +
                        ")");

        // 查询
        tEnv.executeSql("desc ywb_source").print();
        tEnv.executeSql("SELECT * FROM ywb_source").print();

分析：

根据报错信息显示，在zk中没有配置hbase节点，或者说hbase在zk中配置的节点名称不是/hbase，所以先查看habse-site.xml文件，结果如下：

    <property>
      <name>zookeeper.znode.parent</name>
      <value>/hbase-unsecure</value>
    </property>

由此可知，hbase在zk中配置的节点名称是/hbase-unsecure，将这个配置填入到hbase连接器中，错误解决。 更正建表sql：

tEnv.executeSql(
                "CREATE TABLE ywb_source (\n" +
                        " rowkey STRING,\n" +
                        " info1 ROW<name STRING>,\n" +
                        " info2 ROW<age STRING>,\n" +
                        " PRIMARY KEY (rowkey) NOT ENFORCED\n" +
                        ") WITH (\n" +
                        " 'connector' = 'pa-hbase',\n" +
                        " 'table-name' = 'ywb_t1',\n" +
                        " 'zookeeper.quorum' = '10.100.2.191:2181',\n" +
                        // 新增连接器配置
                        " 'zookeeper.znode.parent' = '/hbase-unsecure'" + 
                        ")");
