解决方法：在~/.storm/目录新建storm.yaml文件，~代表用户主目录。storm.yaml文件内容：nimbus.host: "10.0.0.24"。重启nimbus后台程序，异常消失。

 

错误2：启动Supervisor时，出现java.lang.UnsatisfiedLinkError: /usr/local/lib/libjzmq.so.0.0.0: libzmq.so.1: cannot open shared object file: No such file or directory异常。异常内容如下所示：

解决方法1：export LD_LIBRARY_PATH=/usr/local/lib

解决方法2：编辑/etc/ld.so.conf文件，增加一行：/usr/local/lib。再执行sudo ldconfig命令，重启Supervisor，异常消失。

 

错误3：发布drpc类型的topologies到远程集群时，出现空指针异常，连接drpc服务器失败。

 

解决方法：在conf/storm.yaml文件中增加drpc服务器配置，启动配置文件中指定的所有drpc服务。内容如下所示：

drpc.servers:

  - "drpc服务器ip"

 

错误4：客户端调用drpc服务时，worker的日志中出现Failing message，而bolt都未收到数据。日志如下所示：

2011-12-02 09:59:16 task [INFO] Failing message backtype.storm.drpc.DRPCSpout$DRPCMessageId@3770bdf7: source: 1:27, stream: 1, id: {-5919451531315711689=-5919451531315711689}, [foo.com/blog/1, {"port":3772,"id":"5","host":"10.0.0.24"}]

 

解决方法：主机名，域名，hosts文件配置不正确会引起这类错误。检查并修改storm相关机器的主机名，域名，hosts文件。重启网络服务：service network restart。重启storm，再次调用drpc服务，成功。Hosts文件中必须包含如下内容：

【nimbus主机ip】 【nimbus主机名】 【nimbus主机别名】

【supervisor主机ip】 【supervisor主机名】 【supervisor主机别名】

【zookeeper主机ip】 【zookeeper主机名】 【zookeeper主机别名】

 

错误5：发布topologies时，出现不能序列化log4j.Logger的异常。

解决方法：使用slf4j代替log4j。 

 

错误6：bolt在处理消息时，worker的日志中出现Failing message。

 

解决方法：提交Topology时设置适当的消息的超时时间，比消息原本的超时时间更长，如下所示：

                     conf.setMessageTimeoutSecs(60);//默认为30秒。
