最近在部署storm on yarn ，部署参考文章
http://www.tuicool.com/articles/BFr2Yvhttp://blog.csdn.net/jiushuai/article/details/18729367
在安装完zookeeper，配置好storm 和storm on yarn后，启动zookeeper，其中zookeeper的port为2181,然后通过mvn package 编译工程，发现会出现错误，然后使用mvn packet -DskipTests 重新编译，跳过test然后向yarn 提交storm任务，storm-yarn launch <path to your storm.yaml file>
提交后查看localhost:8088,发现任务failed，查看错误信息发现错误如下Application application_1411179375629_0005 failed 2 times due to AM Container for appattempt_1411179375629_0005_000002 exited with exitCode: 1 due to: Exception from container-launch: org.apache.hadoop.util.Shell$ExitCodeException: org.apache.hadoop.util.Shell$ExitCodeException: at org.apache.hadoop.util.Shell.runCommand(Shell.java:505) at org.apache.hadoop.util.Shell.run(Shell.java:418) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:650) at org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor.launchContainer(DefaultContainerExecutor.java:195) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:283) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:79) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) Container exited with a non-zero exit code 1 .Failing this attempt.. Failing the application.
查看log信息发现具体错误如下
14/09/19 20:44:55 INFO yarn.MasterServer: Starting Master Thrift Server
14/09/19 20:44:55 ERROR auth.ThriftServer: ThriftServer is being stopped due to: org.apache.thrift7.transport.TTransportException: Could not create ServerSocket on address 0.0.0.0/0.0.0.0:9000.

在启动Master Thrift Server时发生错误，错误为端口错误，因为9000端口已经被hdfs占用监听，因此不能创建ServerSocket
致谢google，搜到的解决办法为修改端口号，帖子如下
https://groups.google.com/forum/#!topic/storm-yarn/A1ds1M6qmN8
修改storm-yarn-master/src/main/resources/master_defaults.yaml，将其中的master.thrift.port修改为一个其他的合适的值，我修改为9001
然后再编译工程，重新提交，这时发现任务没有failed，但是访问localhost:7070，不能访问，查看log后发现错误为nimbus没有启动成功，错误如下：
15/07/15 03:36:06 ERROR yarn.MasterServer: Unhandled error in AM:

意思是申请的virtual cores超过最大限制maxVirtualCores，google后找到帖子
hadoop - Why cannot more than 32 cores be requested from YARN to run a job? - Stack Overflow
http://stackoverflow.com/questions/29780401/why-cannot-more-than-32-cores-be-requested-from-yarn-to-run-a-job
因此修改yarn-site.xml如下
<property> <name>yarn.nodemanager.resource.cpu-vcores</name> <value>8</value> </property>
重新启动yarn，然后提交，成功！！！
如果发现以下错误
2015-07-15 03:19:28 o.a.z.ClientCnxn [INFO] Opening socket connection to server MMC/192.168.1.200:2181 2015-07-15 03:19:28 o.a.z.ClientCnxn [WARN] Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect java.net.ConnectException: 拒绝连接
有可能是zookeeper没有启动，启动即可
时刻注意自己的防火墙有没有关闭，有些不知名的原因是因为防火墙没有关闭造成的！
用了三四天时间才解决了这个问题，期间走了不少弯路，因为刚开始接触hadoop storm on yarn，因此有时候出错误了不知道怎么去查错，开始时只是自己估计是哪出了问题，然后改一下重新跑一下，结果还是不行，后来学会了去查错误log，在masterhost：8088/logs/下就是所有的错误日志，然后查找相关的错误日志排错事半功倍
致谢：google
