Which file are you supplying in the step? Hostdetail.txt or hosts? From: xupeng.bupt [mailto:[email protected]] Sent: Thursday, August 09, 2012 11:33 AM To: ambari-user Subject: Re: RE: Problem when setting up hadoop cluster step 2
Thank you for your replying ~ I made only one hostdetail.txt file which contains the names of all servers. And i submit this file on the website , but i still have the same problem. I failed at the step of finding reachable nodes. The error log is : " [ERROR][sequentialScriptExecutor][sequentialScriptRunner.php:272][]: Encountered total failure in transaction 100 while running cmd: /usr/bin/php ./addNodes/findSshableNodes.php with args: EBHadoop root 35 100 36 /var/run/hmc/clusters/EBHadoop/hosts.txt " And my hostdetail.txt file is :" vbaby2.cloud.eb vbaby3.cloud.eb vbaby4.cloud.eb vbaby5.cloud.eb vbaby6.cloud.eb " Thank you very much ~ 2012-08-09 ________________________________ xupeng.bupt ________________________________ 发件人： Artem Ervits 发送时间： 2012-08-09 22:16:53 收件人： [email protected]<mailto:[email protected]> 抄送： 主题： RE: Problem when setting up hadoop cluster step 2 the installer requires a hosts file which I believe you called hostdetail. Make sure it's the same file. You also mention a hosts.txt and host.txt. You only need one file with the names of all servers. -----Original Message----- From: xu peng [mailto:[email protected]]<mailto:[mailto:[email protected]]> Sent: Thursday, August 09, 2012 2:02 AM To: [email protected]<mailto:[email protected]> Subject: Problem when setting up hadoop cluster step 2 Hi everyone : I am trying to use ambari to set up a hadoop cluster , but i encounter a problem on step 2.
