最近第一次使用hbase存储大数据，解析hbae-site.xml初始化连接，但是报了上面的异常

异常背景：相同的上线包，部署至预发布环境ok；部署至正式环境异常


中间还报过以下异常：

 2017-02-14 14:37:06.040 http-bio-1601-exec-1  WARN [org.apache.hadoop.util.NativeCodeLoader:62] - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

以上是warn级别，不影响运行

因为我采用的是rpc方式访问hbase+hadoop系统，所以本地访问不到hadoop环境变量，打印了debug日志，不影响运行，忽略。

之前嫌解析xml麻烦，使用了代码初始化的方式：(注意，但是我还是在WEB-INF/classes目录下保留了之前的hbase-site.xml文件！！！)

在预发布环境也是ok的，以为没问题，就部署到正式环境，没想到报了下面的错：

看到这些，我毫不犹豫的怀疑是包冲突，急急忙忙去检查包冲突问题，费了半天无果而终。。。


最后回过来仔细分析堆栈，Caused by: java.net.ConnectException: Connection timed out，这个连接异常应该才是主要原因，并且堆栈里面很明显是在jdk内部异常——解析xml时出现的连接超时。

但是xml文件在预发布环境也是可以运行 的吗？为啥正式环境不行呢？并且我是通过代码方式初始化，应该不会解析xml吧？一团疑惑，但还是抱着碰碰运气的想法再仔细检查了下xml，发现xml的一个标签头：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/2002/xmlspec/dtd/2.10/xmlspec.dtd">
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
	
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>*****</value>
    </property>

    <!-- 此参数决定了每次从服务器scan获取的数据量，默认会是1，性能很低，因此设置为100以上，每行数据太大的，可以小一些，否则可以更高 -->
    <property>
        <name>hbase.client.scanner.caching</name>
        <value>1000</value>
    </property>

    <!-- 此参数定义访问的hbase集群使用的zookeeper根节点路径 -->
    
    <property>
        <name>zookeeper.znode.parent</name>
        <value>/hbase_hades</value>
    </property>

    <!-- 此参数定义客户端写缓存的大小,这里配置了5M -->
    <property>
        <name>hbase.client.write.buffer</name>
        <value>5242880</value>
    </property>

    <!-- 其他参数根据应用情况配置，请和HBase组讨论具体业务场景-->
    <property>
        <name>bdp.hbase.erp</name>
        <value>***</value>
    </property>

	
    <property>
        <name>bdp.hbase.instance.name</name>
        <value>***</value>
    </property>

    <property>
        <name>bdp.hbase.accesskey</name>
        <value>***</value>
    </property>

    <!--是否切换到备份集群-->
    <property>
        <name>slave.cluster.switch</name>
        <value>false</value>
    </property>
</configuration>


没错，就是标黄的那个头部：
<!DOCTYPE configuration PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/2002/xmlspec/dtd/2.10/xmlspec.dtd">
jdk解析xml的时候会访问

http://www.w3.org/2002/xmlspec/dtd/2.10/xmlspec.dtd


不会是预发布环境可以访问这个外网域名，而正式环境访问不了吧？？
到服务器上ping过后，就是正式环境限制外网权限，解析xml时访问这个头部域名超时引起xml解析失败。。。
看到这里，我都要吐血了。。。

移除这行头部，重启，果断ok，问题解决。


但是。。。。。。
为啥我使用代码初始化，程序还是会去解析xml呢？
为啥一个简单的超时，不打印超时的地址呢？里面疑似包冲突的异常真的很容易误导人。。。
