【特别注意】Sqoop2里面各个版本的区别还是很大的，这里使用1.99.6版本。
sqoop2的url等信息放到properties配置文件中，配置文件解析出来传给SqoopClient报错。SqoopClient初始化代码：
private SqoopUtil() throws IOException { String url = PropertiesUtil.getProperty("SQOOP_URL").trim(); SqoopClient client = new SqoopClient(url); System.out.println("url:" +url); connectorMap = new HashMap<String, Long>(); System.out.println(client.getConnector(2));//注释掉该句不报错 // readConnectorMap(); System.out.println("connectorMap size---------"+ connectorMap.size()); }配置文件解析工具类，解析/myconf.properties文件。
public class PropertiesUtil { private static String propertiesFile = "/myconf.properties"; private static PropertiesUtil proUtil = null; private static HashMap<String, String> confMap= null; private static Properties p = new Properties(); public PropertiesUtil() throws IOException { confMap = new HashMap<String, String>(); readPropertiesToMap(); System.out.println(); } private static void readPropertiesToMap() throws IOException { p.load(PropertiesUtil.class.getResourceAsStream(propertiesFile)); for(Object key: p.keySet()) { confMap.put((String)key, p.getProperty((String)key)); } } private static PropertiesUtil getPropertiesUtil() throws IOException { if(proUtil == null) { synchronized(PropertiesUtil.class) { if(proUtil == null) { long start = System.currentTimeMillis(); proUtil = new PropertiesUtil(); long end = System.currentTimeMillis(); System.out.println("construct properties util last "+ (end-start)); } } } return proUtil; } public String get(String name) throws IOException { return confMap.get(name); } public static String getProperty(String name) throws IOException { return getPropertiesUtil().confMap.get(name); } public static void main(String[] args) throws IOException { System.out.println(getPropertiesUtil().confMap.get("SQOOP_URL")); } }但在调用client.getConnector的时候报错：
将初始化SqoopClient的url改为/myconf.properties文件中的SQOOP_URL对应的字符串则能顺利运行：
暂时还没解决。。。正在研究中。。。
