错误类型1：
错误内容如下：2013-11-12 23:28:31,575 WARN org.apache.zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnectjava.net.ConnectException: Connection refusedat sun.nio.ch.SocketChannelImpl.checkConnect(Native Method)at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:599)at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:350)at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1068)2013-11-12 23:28:31,675 WARN org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper: Possibly transient ZooKeeper exception: org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for hbasemaster2013-11-12 23:28:31,676 INFO org.apache.hadoop.hbase.util.RetryCounter: Sleeping 8000ms before retry #3...2013-11-12 23:28:31,676 INFO org.apache.zookeeper.ClientCnxn: Opening socket connection to server slave002172.25.60.202:2181. Will not attempt to authenticate using SASL (无法定位登录配置)
解决办法：
每个机器都系统时间首先相同，版本一致。再有就是hbase-default.xml 这个文件把所有节点都配进去。
错误类型2：
在XP eclipse中 做J2ee程序连接到 远程 Hbase 。出现异常： 
  1.

解决方法：
1、 配置hosts
由于Hbase是通过hostname解析IP地址的(DNS)，Zookeeper只会返回Hbase的域名，需要客户端通过DNS或本地hosts文件进行解析。
若为Linux，在/etc/hosts文件中添加Hbase Master节点的域名及IP地址映射
若为Windows，修改C:\Windows\system32\etc\hosts文件，添加Hbase Master节点的域名及IP地址映射。
2、做完这部继续运行
还有错误，看控制台信息，报：protobuf-java-2.4.0a.jar 该包未找到。去hbase server上将该包下载下来，加入 classpath ，运行，Debug中还有上述异常，但在最后可以查询出hbase中的值。
3、将Log4J配置文件改为 INFO级别。继续运行。异常信息没有。
4、将 protobuf-java.jar 删除，继续运行该项目，也不抱异常了。查询一切正常。

错误类型3：
把代码拷贝到Hadoop的lib下面，然后在命令行中运行，遇到的一个问题如下：
  • 12/09/29 12:29:36 INFO zookeeper.ZooKeeper: Initiating client connection, connectString=localhost:2181 sessionTimeout=180000 watcher=hconnection
  • 12/09/29 12:29:36 INFO zookeeper.ClientCnxn: Opening socket connection to server /127.0.0.1:2181

  • 12/09/29 12:29:36 INFO zookeeper.RecoverableZooKeeper: The identifier of this process is 6479@fansyPC
  • 12/09/29 12:29:36 WARN zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
  • java.net.ConnectException: 拒绝连接
  • at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method)
  • at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:692)
  • at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:286)
  • at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1035)
  • 12/09/29 12:29:36 WARN zookeeper.RecoverableZooKeeper: Possibly transient ZooKeeper exception: org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/master

配置如下：


  1. <configuration>  

  2.     <property>  

  3.         <name>hbase.rootdir</name>  

  4.         <value>hdfs://fansyPC:9000/hbase</value>  

  5.     </property>  

  6.     <property>  

  7.         <name>hbase.cluster.distributed</name>  

  8.         <value>true</value>  

  9.     </property>  

  10.       

  11.     <property>  

  12.         <name>hbase.zookeeper.quorum</name>  

  13.         <value>slave1</value>  

  14.     </property>  

  15.       

  16.     <property>  

  17.         <name>hbase.zookeeper.property.dataDir</name>  

  18.         <value>/home/fansy/zookeeper</value>  

  19.     </property>  

  20.       

  21. </configuration>

解决方案：
要Ubuntu的系统有点不同的，所以改了下：
/etc/security/limits.conf  ：
添加这两句：
1.hadoop - nofile 32768  
2.hadoop soft/hard nproc 32000  
/etc/pam.d/common-session:
session required pam_limits.so
hbase.zookeeper.quorum
配置不能和slave节点机在一个上面？所以我就又改了这个值 ,全部改为 fansyPC了，同时根据官方文档上面说要用hbase/lib下面的hadoop-core-1.0.2.jar 去代替haoop/下面的hadoop-core-1.0.2.jar这个文件，最后把hbase/lib下面的JAR包都放在了hadoop/lib下面（重复的跳过），然后就Ok了。



错误类型4：
Master上的HMaster服务老是自动死掉, 看错误日志只是提示连接失败Session 0x0 for server null
解决方法:
1. 关闭IP6    , 修改/etc/hosts   注视以"::1 "开头的
2. 校准HBase集群Zookeeper集群机器的时间,误差30秒以内
重启机器.ok
